Notification list enhancements, fix striped tables on dark theme (#24639)

- Make code block rendering via backticks work
- Remove link color unless hovered
- Remove table stripes and fix stripes rendering on dark theme for other
tables
- Introduce new `button-link` class discussed previously for buttons
that look and act like links and apply it to the two right-side buttons
- Reduce box padding by 8px on each side
- Fix "Mark all read" button margin-right
- brighten `--color-markup-code-block` on arc-green
