* Use RSA-2048 key instead of 4096

After bumping jest, the RSA signing performance went down by a factor of
2 or so, which causes tests to fail (since they went from ~3 seconds to
~6 seconds to generate a 4096-bit RSA signature). The tests generate
these signatures to fake responses from GitHub.

After replacing the keys with a 2048-bit key, the signing times are now
under a second.

* Revert unnecessary change to test timeout
