fix(template-no-attrs-in-components): change templateMode 'loose' → 'both'

  The rule applies in both HBS and GJS/GTS — classic @ember/component
  components can be authored in strict mode too, and their templates can
  still leak `this.attrs.*`. Regenerated docs to drop the incorrect
  "HBS Only" note.

-> **HBS Only**: This rule applies to classic `.hbs` template files only (loose mode). It is not relevant for `gjs`/`gts` files (strict mode), where these patterns cannot occur.

 This rule prevents the usage of `this.attrs` property to access values passed to the component. Use `@arg` syntax instead.
