CompatHelper: bump compat for FixedPointNumbers to 0.9, (keep existing compat)

[github-actions]

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

@cormullion could you please take a look into this? It is hold a couple of updates downstream. I can access the Action settings in Colorfy.jl but not in Colors.jl

I can’t test this at the moment.

@cormullion it might suffice to restart the jobs on GitHub. If you are near a machine with GitHub login, that could be an option.

Could someone with write access please help with this update?

I think ColorTypes.jl needs some attention first. I don’t think I’m knowledgeable enough to start merging loads of pull requests in this area, so I’ll pass…

A heads-up before merging: FixedPointNumbers 0.9 is a breaking release, and CompatHelper does not run the tests against the new compat entry. Two behavioral changes are the most likely to affect this package:

• Normed * Normed now wraps on overflow instead of throwing. In 0.8, multiplication between Normed values used checked arithmetic (OverflowError); in 0.9 the default for * (like + and -) is wrapping (modular) arithmetic. /, div, rem, and mod are now checked and throw.
• Fixed combined with an Integer now promotes to a floating-point type (e.g. Q0f7(0.5) + 1 === 1.5f0); in 0.8 the result stayed Fixed. (Normed + Integer already promoted to float in 0.8, so that case is unchanged.)

Also worth knowing: print no longer emits the type suffix and show output changed slightly, which tends to surface in doctests; and Fixed multiplication/division rounding changed (ties-to-even, and / rounds to nearest instead of truncating).

Full notes: https://github.com/JuliaMath/FixedPointNumbers.jl/releases/tag/v0.9.0

Note that ColorTypes needs the equivalent bump (JuliaGraphics/ColorTypes.jl#330) before this one can resolve with 0.9 anyway, since ColorTypes also pins FixedPointNumbers to 0.8.
