adds 'update PR comment' routes to allowlist

[silviutanasa]

Description of the change

As part of CU-8694k6wnq (Allow notification policy to update PR comment in-place) new endpoints were added for the VCSs, in order to update the PR comments.

This change was meant to add support for Bitbucket Data Center, but because it was not known at that time that the new VCS routes must be added to the allowlist, it also add the missing routes for the Azure DevOps and Gitlab. Github enterprise doesn't need to be updated as it uses GraphQL and the main route is already added to the allowlist.

The allowlist NoMatch error message was changed in order to be clearer and avoid being confused with the gock package errors when testing (when trying to mock a HTTP request in tests, if the request URL was not in the allowlist, the test use to failed with "no match for request" which was easily confused to "the request was not properly mocked")
