Artifacts download api for artifact actions v4 (#33510)

* download endpoint has to use 302 redirect
* fake blob download used if direct download not possible
* downloading v3 artifacts not possible

New repo apis based on GitHub Rest V3
- GET /runs/{run}/artifacts (Cannot use run index of url due to not
being unique)
- GET /artifacts
- GET + DELETE /artifacts/{artifact_id}
- GET /artifacts/{artifact_id}/zip
- (GET /artifacts/{artifact_id}/zip/raw this is a workaround for a http
302 assertion in actions/toolkit)
- api docs removed this is protected by a signed url like the internal
artifacts api and no longer usable with any token or swagger
  - returns http 401 if the signature is invalid
    - or change the artifact id
    - or expired after 1 hour

Closes #33353
Closes #32124
