Issue description

With light theme for editor (interface/theme/preset = "Light"), in built-in docs variables and functions use light gray color for highlighting.
Example for bool snippet:

Which should match text editor colors, like here:

It is possible to workaround this, by changing theme to Default, then change back to Light.
Then right colors will be used:

I believe this issue caused by same reasons that I reported in past:
#85633
#85627

Steps to reproduce

1. Start Godot with Light theme.
2. Open any docs and scroll to code snippet.
3. Observe light grey colored text.

Minimal reproduction project (MRP)

Godot editor itself affected.
