Remove Repository License Detection from reliable

What does this MR do and why?

We had a failing test #376154 (closed) in staging when the gitaly_go_find_license was enabled on staging.
The test was written expecting this to cover a scenario where it handles a valid license in go-license-detector but unrecognized in licensee but it seems that it is now working in both.

This isn't a bug in it's current form - it's good that we can detect more licenses - but we need to adjust the test accordingly to cover the mentioned scenario.
Removing this test from reliable until I can investigate this further.
