silverwind 428d72d26f chore: re-enable and extend unescaped-html-literal eslint rule (#39832)
https://github.com/go-gitea/gitea/pull/38046 accidentally dropped
`gitea/unescaped-html-literal` from the eslint config, so it has been
off since. Raised in
https://github.com/go-gitea/gitea/pull/39829#issuecomment-6246720235.

- Re-enable the rule, exempting e2e tests like unit tests
- Detect tags anywhere in strings and template chunks, not only at the
start
- Allow `htmlRaw` templates, they escape like `html`
- Fix the existing violations, which escapes the heatmap tooltip and
shortcut keys
