config: drop git_config_get() wrapper

In 036876a106 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config_get()`. All
callsites are adjusted so that they use `repo_config_get(the_repository,
...)` instead. While some callsites might already have a repository
available, this mechanical conversion is the exact same as the current
situation and thus cannot cause any regression. Those sites should
eventually be cleaned up in a later patch series.
