I have noticed that too many new issues have not used the issue template
in the expected manner. Primarily because most people opening issues are
not accustomed to Github Markdown syntax. So change the template to be
exclusively a comment that provides advice regarding what information
will help the fish community resolve a issue.
- Comment out asciinema - people too often leave a link there.
- "Launch fish" is probably a stupid thing to have a first step.
- Combine the expected/actual result sections, maybe that was too tedious.
Added instructions to try without their configuration/plugins in place on issues template.
Make it clear to future humans which fish version a user is confirming was affected (the current "latest fish")
