Remove `delete!(Pkg.Types.get_last_stdlibs(v"1.6.3"), uuid)` hacks?

[lgoettgens]

We have a bunch of recipes that include the above line, in most cases in a block like

# See https://github.com/JuliaLang/Pkg.jl/issues/2942
# Once this Pkg issue is resolved, this must be removed
uuid = Base.UUID("a83860b7-747b-57cf-bf1f-3e79990d037f")
delete!(Pkg.Types.get_last_stdlibs(v"1.6.3"), uuid)

The referenced issue JuliaLang/Pkg.jl#2942 is closed since last fall, and I think the fix is available in Yggdrasil since the used julia version got bumped from 1.7 to 1.12. Does that mean that we could (or must) remove these hacks from all 27 recipes?

I've tested if the recipe for rustfft succeeds after removing the line and can confirm that it does.
