[Doc]: Reduce references to set_tight_layout #26637
Description
Documentation Link
https://matplotlib.org/stable/api/figure_api.html#matplotlib.figure.Figure.set_tight_layout
Problem
set_tight_layout is deprecated.
galleries/users_explain/axes/tight_layout_guide.py:# time the figure is redrawn, you can call ``fig.set_tight_layout(True)``, or,
lib/matplotlib/figure.py: Whether to use the tight layout mechanism. See `.set_tight_layout`.
lib/matplotlib/figure.py: ``tight_layout=True`` and use `.set_tight_layout` otherwise.
lib/matplotlib/figure.py: decorations do not overlap. See `.set_tight_layout` for
Suggested improvement
Better to point to something else. Not sure if that should be TightLayoutEngine or the tight layout guide or what.
