fix: Remove triage action & add exclude paths

[fredericsimard]

Summary:

Removed triage action because this is now integrated in the new Projects, using Workflows. See : https://docs.github.com/en/issues/planning-and-tracking-with-projects/automating-your-project/using-the-built-in-automations

Also, to prevent the whole process of testing in the end-to-end action because a YAML was changed, added .github/workflows/** to the list of excluded paths.
