71ec568d - Use `git` command to fetch repositories instead of `libgit2` for robust SSH support (#1781)

Use `git` command to fetch repositories instead of `libgit2` for robust SSH support (#1781) Closes https://github.com/astral-sh/uv/issues/1775 Closes https://github.com/astral-sh/uv/issues/1452 Closes https://github.com/astral-sh/uv/issues/1514 Follows https://github.com/astral-sh/uv/pull/1717 libgit2 does not support host names with extra identifiers during SSH lookup (e.g. [`github.com-some_identifier`]( https://docs.github.com/en/authentication/connecting-to-github-with-ssh/managing-deploy-keys#using-multiple-repositories-on-one-server)) so we use the `git` command instead for fetching. This is required for `pip` parity. See the [Cargo documentation](https://doc.rust-lang.org/nightly/cargo/reference/config.html#netgit-fetch-with-cli) for more details on using the `git` CLI instead of libgit2. We may want to try to use libgit2 first in the future, as it is more performant (#1786). We now support authentication with: ``` git+ssh://git@<hostname>/... git+ssh://git@<hostname>-<identifier>/... ``` Tested with a deploy key e.g. ``` cargo run -- \ pip install uv-private-pypackage@git+ssh://git@github.com-test-uv-private-pypackage/astral-test/uv-private-pypackage.git \ --reinstall --no-cache -v ``` and ``` cargo run -- \ pip install uv-private-pypackage@git+ssh://git@github.com/astral-test/uv-private-pypackage.git \ --reinstall --no-cache -v ``` with a ssh config like ``` Host github.com Hostname github.com IdentityFile=/Users/mz/.ssh/id_ed25519 Host github.com-test-uv-private-pypackage Hostname github.com IdentityFile=/Users/mz/.ssh/id_ed25519 ``` It seems quite hard to add test coverage for this to the test suite, as we'd need to add the SSH key and I don't know how to isolate that from affecting other developer's machines.
