gh actions: issues workflow: disable job on forked PR's OR it's an issue

[eguzki]

When the feature branch is in the Kuadrant/kuadrant-operator repo the github action context looks like this:

 "github.repository"  -> Kuadrant/kuadrant-operator
 "github.event.pull_request.head.repo.full_name" -> Kuadrant/kuadrant-operator

when the feature brnach is in another repo (forked one) and opens PR in this repo, the context looks like this:

"github.repository" -> Kuadrant/kuadrant-operator
"github.event.pull_request.head.repo.full_name" -> ilargitxiki/kuadrant-operator

When we want to disable job on PR's coming from forked repos to prevent it from failing (because there is no access to secrets), that is the cleanest way so far.

jobs:
  job_id:
    if: github.event.pull_request.head.repo.full_name == github.repository

Issues workflow will also be run when an issue is being opened.

Note: for some unknown reason, when issues are opened, not matter internal or external collaborator, the ADD_ISSUES_TOKEN secret is available and the issue is being added to the project

Tested:

• External user creates issue ✔️
• Internal collaborator creates issue ✔️
• PR created by internal collaborator ✔️
• PR from forked repo ❎ (not being run, and the workflow succeeds)

Makes sense to me.

Another approach would be to have two workflows, one for issues opened and the other for PR's not coming from forked repos
