Comments difficult to read in pipeline rule "source code editor" when dark mode is used (6.x)

[coffee-squirrel]

Expected Behavior

All text should be easily readable when in dark mode.

For example, under 5.2.7:

Current Behavior

Comments in the pipeline rule "source code editor" are difficult to read when dark mode is used.

Under 6.0.1 (with the same text):

Steps to Reproduce (for bugs)

1. Be on at least 6.0.0 and use dark mode
2. Open the pipeline rule source code editor and add a rule with some comments
3. Note it's somewhat difficult to read the comment text (slightly better when the row is selected)

Context

Not being able to clearly read all text makes working with pipeline rules more difficult under 6.0.x.

Somewhat related: the table header background color is also not great in dark mode under 6.0.x (message tables, Users list, Event Definitions list, etc.). It'd be nice if there was more contrast.
