Rollup merge of #98581 - ehuss:triagebot-mentions, r=Mark-Simulacrum

Add triagebot mentions.

This migrates the configuration of mentions from highfive to triagebot.

I also fixed a few broken paths (error_codes.rs src/librustdoc/html/static/themes src/librustdoc/html/static/themes/ayu.css).

+Hey! It looks like you've submitted a new PR for the library teams!
+
+If this PR contains changes to any `rust-lang/rust` public library APIs then
+please comment with `@rustbot label +T-libs-api -T-libs` to tag it
+appropriately. If this PR contains changes to any unstable APIs please edit
+the PR description to add a link to the relevant [API Change
+Proposal](https://std-dev-guide.rust-lang.org/feature-lifecycle/api-change-proposals.html)
+or [create one](https://github.com/rust-lang/libs-team/issues/new?assignees=&labels=api-change-proposal%2C+T-libs-api&template=api-change-proposal.md&title=%28My+API+Change+Proposal%29)
+if you haven't already. If you're unsure where your change falls no worries,
+just leave it as is and the reviewer will take a look and make a decision to
+forward on if necessary.
+
+Examples of `T-libs-api` changes:
+
+* Stabilizing library features
+* Introducing insta-stable changes such as new implementations of existing
+  stable traits on existing stable types
+* Introducing new or changing existing unstable library APIs (excluding
+  permanently unstable features / features without a tracking issue)
+* Changing public documentation in ways that create new stability guarantees
+* Changing observable runtime behavior of library APIs
