Update g++ and clang versions for Ubuntu 22.04
As pointed out by @Geod24, there’s a few more things we might want to update as well: https://github.com/dlang/dmd/pull/21286#discussion_r2053487522
Not sure whether this works as is as Ubuntu is no longer packaging the vMAJOR.0.0 versions of clang.
Hence filing as a draft.
Thanks for your pull request, @0xEAB!

Alright, we are pulling in blobs. My bad. This will have to be more sophisticated.
@Geod24: What was the motivation for testing all these C++ compiler versions? Was there ever a regression caused/surfacing with a specific C++ compiler version?
To me, it would seem more useful to reduce these tests/jobs, and test recent versions instead. E.g., we could use Ubuntu 24 for Linux, where g++ is available from 9 to 13 (no PPA), and clang from 14 to 18 (by the distro directly, no need to resort to LLVM binaries on GitHub). On macOS, we could e.g. test the ~3 available (major) Xcode versions (as provided by the GHA images) and their Apple clang versions. And on Windows, VS 2019 and 2022 as available from GitHub Action images, plus maybe a few clang versions.

I have a vague memory of wanting to be thorough, and getting burned on a few occasions when implementing template mangling. But to be fair, it was probably down to minor differences that weren't handled properly on our side, and I don't remember a regression being caught, so reducing the coverage would make sense to me too.
I’ll consider my patch superseded by #21295. Thanks for picking this up, @kinke!
Really looking forward to see all the janky blob and PPA stuff go.
