"Install spaCy" webpage, auto-gen pip command line apostrophe issue for CUDA selection

[ah-git]

At the 'Install spaCy' page.
If you select Windows, x86, pip, GPU and CUDA version then the following generated pip command line erroneously has apostrophes added. Removing apostrophes manually seemed to be remedy.
pip install -U 'spacy[cuda12x]'

this worked...

pip install -U spacy[cuda12x]

You're right: this is a command-generator bug, not a spaCy or CUDA packaging problem.

The quickstart currently wraps every pip requirement with extras in POSIX single quotes (source). In cmd.exe, single quotes are ordinary characters, so pip receives the quote marks as part of the requirement. PowerShell understands single quotes, which is why the failure depends on which Windows shell is used.

A portable Windows command is:

py -m pip install -U "spacy[cuda12x]"

Double quotes also work in PowerShell and POSIX shells, and they still prevent shells from interpreting the brackets. Removing the quotes happens to work here because the argument contains no spaces, but emitting double quotes is the safer cross-shell fix. The same generator should use double quotes for its editable source-install extras as well.
