Split up AI filtering files (#592)

* Split up AI filtering files

Create aggressive/moderate/permissive policies to allow administrators to choose their AI/LLM stance.

Aggressive policy matches existing default in Anubis.

Removes `Google-Extended` flag from `ai-robots-txt.yaml` as it doesn't exist in requests.

Rename `ai-robots-txt.yaml` to `ai-catchall.yaml` as the file is no longer a copy of the source repo/file.

* chore: spelling

* chore: fix embeds

* chore: fix data includes

* chore: fix file name typo

* chore: Ignore READMEs in configs

* chore(lib/policy/config): go tool goimports -w
