CompatHelper: bump compat for JET to 0.11 for package docs, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the JET package from 0.9, 0.10 to 0.9, 0.10, 0.11 for package docs.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.
