The AdminPlugin JS model uses a similar pattern to chat models,
where it is a plain JS class manually converting provided
snake_case attributes from the serializer to JS camelCase.
However this doesn't work when it comes to using `add_to_serializer`
in plugins since core does not know about these new attributes.
Instead, we can use a JS function to convert snake_case to camelCase
and use that when initializing AdminPlugin. This commit also moves
similar functions to a new case-converter.js file in
discourse-common/lib.
In 53b3d2f0dc we introduced a stricter BBCode Tag parser. It prevents having "values" with spaces when they're not surrounded by a valid pair of quotes.
The `[details=` BBCode Tag is popular enough that it's worth adding a special case for it (especially since it doesn't support other parameters).
This also adds the Finnish pair of quotes.

Wasn't quite handling the cases where a closing bracket `]` was used in the value of one of the attributes.
```markdown
[chat quote=user channel="[broken]"]
```
Would not be correctly parsed because we would _greedily_ use the first `]` as the end of the tag even though it might be a valid character when inside proper quotes.

Re-wrote the `parseBBCodeTag` to properly handle the following cases
- A closing tag (aka `[/name]`) which are easy since they don't have any attributes
- An old `[quote=...]` format we used that doesn't uses quotes but still has various attributes of the form `key:value`
- All three valid BBCode opening tag formats we support
- `[name]` without any attributes
- `[name=foo]` with a default value
- `[name foo=bar]` with some attributes
Ended up having to fix/rewrite the few bbcode rules that were using the `parseBBCodeTag` function, namely `d-wrap` and `discourse-local-dates`.
While working on this, I think I also found a way to get rid the of shims we had in place so that plugins could use the `parseBBCodeTag` function.

Inline the helper functions, avoid creating and then immediately destructuring arrays, use complete strings instead of string interpolation, Map instead of a pojo.
> [code]
> line1
> line2
> [/code]
would render as
| line1
| > line2
instead of the correct
| line1
| line2
That was due to the `bbcode-block` code using a `slice` to get the content of a block and not taking into account it being nested in a quote block for example.
The fix was to get the content using the `getLines` utils method.

- Remove vendored copy
- Update Rails implementation to look for language definitions in node_modules
- Use webpack-based dynamic import for hljs core
- Use browser-native dynamic import for site-specific language bundle (and fallback to webpack-based dynamic import in tests)
- Simplify markdown implementation to allow all languages into the `lang-{blah}` className
- Now that all languages are passed through, resolve aliases at runtime to avoid the need for the pre-built `highlightjs-aliases` index
With Embroider, we can rely on async `import()` to do the splitting
for us.
This commit extracts from `pretty-text` all the parts that are
meant to be loaded async into a new `discourse-markdown-it` package
that is also a V2 addon (meaning that all files are presumed unused
until they are imported, aka "static").
Mostly I tried to keep the very discourse specific stuff (accessing
site settings and loading plugin features) inside discourse proper,
while the new package aims to have some resembalance of a general
purpose library, a MarkdownIt++ if you will. It is far from perfect
because of how all the "options" stuff work but I think it's a good
start for more refactorings (clearing up the interfaces) to happen
later.
With this, pretty-text and app/lib/text are mostly a kitchen sink
of loosely related text processing utilities.
After the refactor, a lot more code related to setting up the
engine are now loaded lazily, which should be a pretty nice win. I
also noticed that we are currently pulling in the `xss` library at
initial load to power the "sanitize" stuff, but I suspect with a
similar refactoring effort those usages can be removed too. (See
also #23790).
This PR does not attempt to fix the sanitize issue, but I think it
sets things up on the right trajectory for that to happen later.
