Add CSS to clock module to prevent line breaking of sunrise/sunset information (#3816)

1. Base your pull requests against the `develop` branch.
Done
2. Include these infos in the description:
- Does the pull request solve a **related** issue?
No
- If so, can you reference the issue like this `Fixes #<issue_number>`?
N/A
- What does the pull request accomplish? Use a list if needed.
With some combinations of sunrise and sunset times (usually when the
time till rise/set is >9:59), the information will break across multiple
lines. This prevents that by adding CSS.
- If it includes major visual changes please add screenshots.
I don't consider it major.
3. Please run `npm run lint:prettier` before submitting so that style
issues are fixed.
Done
4. Don't forget to add an entry about your changes to the CHANGELOG.md
file.
Done
