CLN: 29547 replace old string formatting

[3vts]

I splitted PR #31844 in batches, this is the last
For this PR I ran the command grep -l -R -e '%s' -e '%d' -e '\.format(' --include=*.{py,pyx} pandas/ and checked all the files that were returned for .format( and changed the old string format for the corresponding fstrings to attempt a full clean of, #29547. I may have missed something so is a good idea to double check just in case

• [ x ] tests added / passed
• [ x ] passes black pandas
• [ x ] passes git diff upstream/master -u -- "*.py" | flake8 --diff
• [ x ] Ref Replace old string formatting syntax with f-strings #29547

* [ x  ] tests added / passed

* [ x ] passes `black pandas`

* [ x ] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

* [ x ] closes #29547 (?)

@3vts Can you please change the last line from Closes #29547 to Ref #29547, Just so it won't close the master issue

Thanks for the revert of the None stuff, but why the revert of the repr() changes?

Thanks @3vts lgtm. @MomIsBestFriend

LGTM

See comment on repr changes - should just use quotes instead

Thanks @3vts

General comment - would be nice to keep PRs more minimal in the future. This was maybe an exception because of all of the double curly braces at play, but if something else comes up the same in the future should tackle in smaller bits
