Fix Project.toml UUID

[tkf]

It looks like the UUID in Project.toml is different from the one in the registry: https://github.com/JuliaRegistries/General/blob/master/S/SIMD/Package.toml

This PR make ]test SIMD works after ]dev SIMD, although I remember it worked before... Maybe something changed in Pkg.jl? Anyway, I think it's better to match the UUID.

I don't understand what is happening here. Changing the UUID seems like a drastic step that might have negative consequences as well. Can you inquire on the mailing list why this might have happened, and what the recommended resolution is?

[tkf]

How did you create Project.toml? If you used Pkg.generate()/]generate, it explains why it has a different UUID since Pkg.generate generates a random UUID whereas packages that to be registered have to use Pkg.METADATA_compatible_uuid which gives us

julia> Pkg.METADATA_compatible_uuid("SIMD")
UUID("fdea26ae-647d-5447-a871-4b548cad5224")

(as in https://github.com/JuliaRegistries/General/blob/master/S/SIMD/Package.toml). Also, it looks like UUID in Project.toml is ignored during registration (and also during tagging?) JuliaRegistries/General#22 so maybe that's why there was no error in the latest releases.

It was wrong from the start (c852caf).

what the recommended resolution is?

@fredrikekre Thanks for confirming that!
