DOC (string dtype): update user guide page "Working with text data"

[jorisvandenbossche]

With the new default string dtype in pandas 3.0, we should update the documentation to properly reflect this. The main page about working with string data is https://pandas.pydata.org/pandas-docs/version/2.2/user_guide/text.html

This page currently mentions object dtype vs nullable StringDtype, some differences, and then shows most examples using dtype="string".

We should update that page to reflect that there is now a default "str" dtype, add a historical note about object dtype being the default before pandas 3.0 (and that you can still encounter this, and then how to convert to str dtype; and refer to the upgrade guide), mention the differences of "str" vs "string" dtype, etc

@jorisvandenbossche @mroeschke Should all instances of dtype="string" in the documentation be changed to dtype="str" to align with the new default string dtype in pandas 3.0?

@mroeschke I want to work on this, please guide me.

Not blindly all of them, because in some places it might be explaining something explicitly about the nullable "string" version. But where it is in general about string data, I think indeed it can be changed.

Alright, Thank you. I will work on it.
