Code Blob search result keyword highlighting!
Follow up of #23750 (moved) and should only be done when that one is completed.
To help users read the results we give them I propose we add line highlighting + bold key word highlighting to those results.
Design
- Highlight the whole line, plus number line (number itself stays the same color .. (similar to diff highlighting)
- Key word gets bold mono space font
