Zoltan Kochan d2ed60afba test: make git-resolver and dlx git tests immune to GitHub flakiness (#12885)
The git-resolver unit tests hit live github.com by default: the mocks for
fetchWithDispatcher and graceful-git existed, but beforeEach restored the
real implementations. When GitHub throttles the shared CI runner IPs, the
HEAD probe in isRepoPublic() fails (it has zero retries and treats any
error as "private"), and resolution silently degrades from the hosted
tarball to a git clone, changing the resolved id and failing the
assertions. This broke the main branch build at
https://github.com/pnpm/pnpm/actions/runs/29026897310/job/86153736091

The mocks are now the default: fetch reports every repository as public
and graceful-git serves ls-remote output from a fixture table captured
from the real repositories, with the same commit hashes the assertions
already expected. The private-repo-over-HTTPS test now calls
mockFetchAsPrivate() explicitly instead of relying on a real 404 for the
nonexistent github.com/foo/bar. The one live-network case in
parsePref.test.ts got the same treatment. The suite drops from ~40s to
under half a second and runs offline.

The dlx e2e test stays a genuine end-to-end test against GitHub, but its
allowBuild list now approves both resolution shapes of the same commit
(codeload tarball and git+https clone), so the resolver's
rate-limit-induced fallback no longer trips the
GIT_DEP_PREPARE_NOT_ALLOWED gate, as seen in
https://github.com/pnpm/pnpm/actions/runs/29029971938/job/86170695840
