Fix configuration issue in CI runners (#23223)

While working on PR #23117, I noticed that the Windows runner in our CI
setup doesn't seem to respect the settings defined in
`.cargo/config.toml`. With @SomeoneToIgnore ’s help, Kirill and I
realized this issue isn’t limited to the Windows runner—all of our
runners disregard the configurations in `.cargo/config.toml`.

Later, @osiewicz suggested an excellent workaround. I conducted some
tests on PR #23117 and found that the solution works as intended.

Personally, I prefer using environment variables for global
configuration. However, according to the documentation
[here](https://doc.rust-lang.org/cargo/reference/config.html), it seems
that environment variables always override the settings in
`.cargo/config.toml`.

Release Notes:
