Pygments 2.20 was released today:
It added support for both t-strings and TOML 1.1. Great!
But PEP 501 was withdrawn, so the syntax it proposed wasn't implemented. PEP 750's t-strings was. And Pygments now tries to parse t-strings, but breaks on some suggested 501 syntax. Instead, let's
mark this block as plain text to avoid parsingforce it to build.And turns out some TOML in PEP 751 was invalid, and accidentally missed closing braces. Not noticed before, because Pygments never tried to parse it. Let's just fix it.
See #4877 (comment) and https://github.com/python/peps/actions/runs/23715290614/job/69083117194?pr=4877 for the build failures.
