DOC (string dtype): updated 'Working with text data' for str dtype in pandas 3.0
Closes #60348 

This PR updates the "Working with Text Data" page in the pandas documentation to reflect the change in pandas 3.0 where "str" dtype is now the default.
pre-commit.ci autofix Hi @mroeschke, I've made some updates to the 'text.rst' file which updated 'Working with text data' for str dtype in pandas 3.0

I noticed that after updating the branch, a commit for expressions.py was added, although I have made no commits in the file. Could you please help me understand the changes and guide me through?


 I have made changes according to the review, but somehow I can't revert the changes in expressions.py. Can you please help me with it? > I have made changes according to the review, but somehow I can't revert the changes in expressions.py. Can you please help me with it?

You can open the file with an editor and manually modify the file undoing the changes. Locally, you can run

    git diff upstream/main pandas/core/computation/expressions.py

and keep making modifications until that reports no differences.

If you'd like, I can push a commit undoing the changes there. > If you'd like, I can push a commit undoing the changes there.

It would be very helpful, Thank you.

I have made the changes as per the review, please let me know if there are any other modifications required in the documentation. @rhshadrach, is everything alright, or are modifications needed?
