Add light & dark themes to YAML editor

[gzdunek]

Closes #25413

I would like to merge it before 13.2 release.

I added data visualisation colors (Figma) and replaced the hardcoded values in the terminal theme.
Then I added a theme object for the editor. We can't use data visualisation colors directly, because for the dark theme we have to use tertiary colors, and for the light theme the primary ones.

When I first implemented this, I didn't realize that TextEditor is used not only in the role editor, but also in some Discover screens. I verified how does it look like, and unfortunately it looked bad:

The background color we used was the same as the page background :(

I talked about this with Kenny, and he decided to use depth 3 in a standalone editor, and when displayed inline, depth 4.

I also simplified theming of the ace editor, instead of importing and overwriting ace-monokai I just provided ace-teleport theme.

@ryanclark could you take a look at it one more time? 🙏
