GH-135499 is a backport of this pull request to the 3.14 branch.

@MeGaGiGaGon Can you prepare a 3.13 backport? The comment on the make-a-PR page details how to adjust the title and message. Make sure to prepare using 3.13 branch and compare to 3.13 on the make-a-PR page. If you do not understand, I can fix but wrong title will be a test error.

Both lines to be corrected are 10 lines earlier, but this is not the issue. The merge conflict is that on the crossinterp.c lines, what is 'c-string' now and in 3.14 is 'f- string' in 3.13. So make same 2 changes on otherwise same 2 lines. I consider the blurb for a typo to be optional.
