ci: move error pages outside of the public-api group (#49770)

Currently, a change in an error guide triggers a review for the `public-api` group (requests 3 reviewers and al least 2 must approve). This is overly aggressive and we can relax this by moving the guides under `fw-core` and extended diagnistics under `fw-compiler`. In this case 1 reviewer would be requested.
