[BUG] default syntax highlighting of yaml is unreadable in light terminals

[xton-stripe]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug
Default yaml rendering is unreadable on a light mode (black on white) terminal. It appears to be using the default text color for some elements which blends in with the syntax's background.

MRE:

printf "---\nfoo: bar" | python -m rich.syntax - -x yaml

Note: I'm able to work around this by adding style="white" to the rendering of the syntax block. e.g.:

            s = Syntax(txt, type)
            self.console.print(s, style="white")

(I was hoping that #3132 would fix this, but it still repros in 13.5.3 which has that fix)
