DOC: Show and correct default alignment parameters in text.py (matplotlib#27346)

* Show and correct default alignment parameters in text.py

For issue [Doc]: text alignment defaults matplotlib#27345

* Update text.py: line too long

* Show defaults in text_alignment.py

* Make setter method defaults match new docstrings in text.py

See matplotlib#27346 (review)

* IDL text alignment set_ method defaults for text.pyi

* revert interface defaults in text.pyi

* revert defaults in alignment set_ methods text.py

did change the order of allowed arguments for set_verticalalignment per @StefRe

* Document  text alignment defaults in _axes.py

Because this is where the header at https://matplotlib.org/devdocs/api/_as_gen/matplotlib.pyplot.text.html comes from.

* rm trailing whitespace in _axes.py
