triagebot: Autolabel relevant PRs with `A-rustdoc-js`

[lolbinarycat]

we have an autolabel rule for A-rustdoc-search, but the other few js files lack autolabel rules.

i suppose we do have rules for T-rustdoc-frontend, but that's quite a bit more broad.

---

In triagebot.toml, add an [autolabel."A-rustdoc-js"] rule where field trigger_files should contain directories and files containing JavaScript / TypeScript files and maybe tests/rustdoc-js/ and tests/rustdoc-js-std/ as well.

Hi, is anyone working on this (and is this still needed) ? If folks don't mind, could I work on this ? I've been wanting to start contributing to Rust so I was hoping to pick a starting issue.

[lolbinarycat]

Yes, this would still be appreciated. Tag me in the PR when you create it.

[RishiSastry]

Thank you, yes will do!
