Ivan Batsulin 76f8441b45 feat: add warning news type and Firefox performance notice (#3680) ...

## Description:
Adds a new `warning` news type to the news banner system and uses it to
display a Firefox performance notice.

Changes:
- Added `warning` type with red styling to `NewsBox.ts`
- Added `news_box.warning` key (`"WARNING"`) to `en.json`
- Added Firefox performance notice to `resources/news.json` using the
new `warning` type
- Added `news_box.*` dynamic key pattern to `TranslationSystem.test.ts`
to fix unused key detection

## Please complete the following:
- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
