commit e9219b88de5ed37af337ee2d2e71e7ec7c0aad1b
Author: Robbert van Ginkel <rvanginkel@buf.build>

Fix git unit test by using fake git server rather than file:// (#1518)
More recent versions of git fix a CVE by disabling some usage of the
`file://` transport, see
https://github.blog/2022-10-18-git-security-vulnerabilities-announced/#cve-2022-39253.
We were using this transport in tests.
Instead, use https://git-scm.com/docs/git-http-backend to serve up this
repository locally so we don't have to use the file protocol. This
should be a more accurate tests, since we mostly expect submodules to
come from servers.
