This isn't strictly needed, just a drive-by change as Ubuntu 20.04 will be EOL'ed by GH Actions eventually, and we have no reason to stick to the old version for Web builds.

I'll refactor this logic in #80719 after this is merged.

Just noticed in the 3.x branch that we use tuple(get_compiler_version(env)) there, which is nicer. I'm changing it to that when cherry-picking, and for master I'll refactor later.

Edit: That can't be done for 4.x, there's more than just (major, minor, patch) in the dict.
