Rollup merge of rust-lang#132529 - ismailarilik:ci/triagebot/fix-name-of-trigger-file-LICENSES, r=Mark-Simulacrum

ci(triagebot): add more top-level files to A-meta

It didn't exist so I changed it with its new versions: `COPYRIGHT`, `LICENSE-APACHE` and `LICENSE-MIT`

I also added some other files I found appropriate under the related label.
