This will be default in Ruby 3, so will be good to apply in QA ahead of

There was a bug that required credentials when using SSH key auth when
using LFS. That bug was fixed so we shouldn't need to add credentials to
.netrc when using SSH anymore.

Avoid having to remember to call try_add_credentials_to_netrc
after setting credentials.

Adds a new end-to-end test to check that Git protocol v2 can be used to
push over SSH.

Includes a change in Git::Repository to use Runtime::Env.debug? to
enable logging instead of .verbose?
