incorrect anchor in python3.9

[trysten]

Documentation style bug

Summary

bad anchor in glossary

Actual style

python (3.9) glossary entry f-string has a link to formatted string literals with anchor #f-strings which doesn't scroll to any section because it's not present.

Expected style

anchor index-24 is needed to go to the correct section:
