Workflows: Disable triage labels for collaborators

[armsnyder]

Description

Fixed some annoyances fighting with automation over labels.

• Issues opened by collaborators now won't get labels added (e.g. "needs-triage")
• Comments from collaborators now won't cause labels to be removed (e.g. "waiting-response")

Tested in my fork 👍

PR Checklist

• Resource attributes match 1:1 the names and structure of the API resource in the GitLab API documentation.
• Examples are updated with:
  • A *.tf file for the resource/s with at least one usage example
  • A *.sh file for the resource/s with an import example (if applicable)
• New resources have at minimum a basic test with three steps:
  • Create the resource
  • Update the attributes
  • Import the resource
• No new //lintignore comments that came from copied code. Linter rules are meant to be enforced on new code.
