chore: upgrade to reqwest 0.12.4 and rustls 0.22 (#24056)
This commit updates Deno to use `reqwest` at 0.12.4
and `rustls` at 0.22. Other related crates were updated
as well to match versions accepted by `reqwest` and `rustls`.

Note: we are not using the latest available `rustls` yet,
but this upgrade was non-trivial already, so a bump to
0.23 for `rustls` will be done in a separate commit.

Closes #23370
