With the new admin sidebar restructure, we have a link to "Installed plugins". We would like to ensure that when the admin is searching for a plugin name like "akismet" or "automation" this link will be visible. Also when entering the plugins page, related plugins should be highlighted.
Followup to e37fb3042d
Some plugins like discourse-ai and discourse-saml do not
nicely change from kebab-case to Title Case (e.g. Ai, Saml),
and anyway this method of getting the plugin name is not
translated either.
Better to use the plugin setting category if it exists,
since that is written by a human and is translated.
* Remove checkmark for official plugins
* Add author for plugin, which is By Discourse for all discourse
and discourse-org github plugins
* Link to meta topic instead of github repo
* Add experimental flag for plugin metadata and show this as a
badge on the plugin list if present
