git-fetch-with-cli: Set GIT_DIR for bare repository compatibility (#14860)

When using `net.git-fetch-with-cli = true` , Cargo fails to clone the
git repository into the cache because `safe.bareRepository` defaults to
`explicit`. This results in an error stating that a bare repository
cannot be used.

This patch sets the `GIT_DIR` environment variable to the correct
repository path instead of removing it. This ensures that Git uses the
correct repository directory and avoids the "cannot use bare repository"
error.

Fixes #14758
