CompatHelper: bump compat for StatsFuns to 1, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the StatsFuns package from 0.7, 0.8, 0.9 to 0.7, 0.8, 0.9, 1.
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.

StatsModels then GLM first need to bump combat for StatsFun v1.0.
