⚠️ Switch RepoClient file access to io.ReadCloser (#3912)
* change file access method to io.ReadCloser

callers don't always need the full file.
large files are slow and can cause crashes.

Signed-off-by: Spencer Schrock <sschrock@google.com>

* switch tests to hardcoded readers

Previously they returned bytes or strings, which have corresponding NewReader types.
Since they don't need to be closed, io.NopCloser works well to give them a fake Close.

* switch tests which called os.ReadFile to os.Open

os.File fufills io.ReadCloser, so this is an easy change

* break tarball tests into two steps: reader and read

The rest of the test was kept the same to minimize the change.

* appease linter during refactor

* switch git client to new method

add check which ensures git client fulfills the interface
