CompatHelper: bump compat for JuliaBUGS in [weakdeps] to 0.10, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the JuliaBUGS package from 0.8, 0.9 to 0.8, 0.9, 0.10.
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.

v0.10 refactors pretty heavily. I'll try making a PR on Wednesday to starts the migration.
