Changed API endpoint from access: 'internal' to access: 'public' (#190316)

## Summary
Changed acces to `public` for
`/internal/security/analytics/_record_violations` endpoint.

Kibana reports Content-Security-Policy (CSP) violations and
Permission-Policy violations to the
`/internal/security/analytics/_record_violations` endpoint. This
endpoint was marked as `internal`, which didn't work because reports are
sent by browser.
