[issue40148] Add PurePath.with_stem()

[Qi Yao]

Qi Yao  added the comment:

In Pathlib, we have functions "with_name()""with_stem()""with_suffix()" to 
modify the file name in the path.

In issue21798:"Allow adding Path or str to Path", it actually also want to 
modify the file name, that is "appand string to file name".

if with_stem() more cumbersome as:
path.with_name(path.stem + '_v2' + path.suffix)

why not have a function with_() more cumbersome as:
path.with_name(path.name + "_name.dat")

I personally would rather not add more methods that are doing simple string 
manipulations.

[issue40148] Add PurePath.with_stem()

[Tim Hoffmann]

New submission from Tim Hoffmann :

Similar to PurePath.with_name() and PurePath.with_suffix() there should be a 
PurePath.with_stem().

A common use case would be appending something before the suffix: 
path.with_stem(path.stem + '_v2')

As of now this must be written more cumbersome as:
path.with_name(path.stem + '_v2' + path.suffix)
