CompatHelper: bump compat for ForwardDiff in [weakdeps] to 1, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the ForwardDiff package from 0.10 to 0.10, 1.
This keeps the compat entries for earlier versions.

It is your responsibility to make sure that your package tests pass before you merge this pull request.
