Consider adding pyogrio example

[Nowosad]

"geopandas uses GDAL to read and write data, via fiona (the default) or pyogrio packages (a recently developed alternative to fiona, which will become the default in the future, see note in "Reading and writing files" tutorial)."

Currently, we show some fiona examples (https://py.geocompx.org/07-read-write) -- however, shouldn't we replace them with pyogrio examples (more future-proof)?
