CompatHelper: bump compat for FHist to 0.11, (keep existing compat)

[github-actions[bot]]

This pull request changes the compat entry for the FHist package from ^0.10 to ^0.10, 0.11. 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.

Yeah don't do this I need to test it first

Do we want to ditch FHist 0.10 support? My workflows are now broken, I adopted FHist 0.11 too early 😆

[Moelf]

I think we can support both -- technically only the constructor is broken in FHist.jl v0.11, so as long as we return the histograms from UnROOT.jl it should be fine?

[tamasgal]

You mean checking the version of FHist.jl and use the corresponding constructor?

[Moelf]

Yes
