chore: upgrade eslint plugins, remove eslint-plugin-github

- Upgrade `typescript-eslint` to 8.61 and `eslint-plugin-unicorn` to 65,
  configuring the rules introduced in unicorn 65.
- Remove `eslint-plugin-github` and its workarounds: rules, the type-stub
  module declaration, the pnpm peer-dependency override, and the in-code
  `eslint-disable` comments that referenced its rules.
- Remove rules deprecated or deleted in their plugins and switch to their
  replacements (e.g. `prefer-single-call`, `no-object-constructor`,
  `id-denylist`, `no-unnecessary-slice-end`).
- Apply the resulting autofixes, mainly wrapping interpolated values in CSS
  selectors with `CSS.escape()`.
