Temporarily disable CodeQL analysis

https://github.com/github/codeql-go/pull/184 added a regression test for the non-termination it was fixing. The fix hasn't made it into Code Scanning yet, so for the time being it will fail with precisely that non-termination when analysing the regression tests.
