Description

This PR removes a test that was both trying to simulate an error that can't happen, and causing bizarre failures elsewhere. For example, when another test failed (simulated with a t.FailNow in Test_GetMe, it would also get this panic:

➜  github-mcp-server git:(main) go test -count=1 ./pkg/github
--- FAIL: Test_GetMe (0.00s)

This is because:

			mockedClient: mock.NewMockedHTTPClient(
				mock.WithRequestMatch(
					mock.GetReposContentsByOwnerByRepoByPath,
				),
			),

Was registering a handler with no responses which would then panic here when a request came in: https://github.com/migueleliasweb/go-github-mock/blob/dd6b28752862d0748bf5cee28fc1d69b0475eb3f/src/mock/server.go#L40-L45

Unfortunately, this panic would never bubble up a test failure in this test, but presumably because it was in a goroutine, would asynchronously result in strange failures in other places. Haven't totally dug into why because it's not that important beyond fixing it.

Also, this expectError field is never actually used because all the tests set expectedErrorMsg.
