MAINT: Add Zizmor as GHA

[VeckoTheGecko]

• Closes None

The changes in the CI are copy paste from their docs

https://docs.zizmor.sh/integrations/#via-zizmorcorezizmor-action

---

This change is because the pre-commit context does not have access to a GitHub Token - which is used by Zizmor (e.g., to validate that projects have the same SHA pin as the version in the comment next to the pin)
