ENH: Add Windows support to pixi.toml + pixi.lock

[N-Dekker]

pixi.lock was regenerated locally on a Windows 10 laptop, by

pixi.exe install -a

@thewtex Thanks for explaining this mechanism! By the way, it still produces a warning, on Windows:

WARN The activation script 'D:\src\ITKElastix\itk_wasm_env.bash' does not have the correct extension for the platform 'win-64'. The extension should be '.bat'.

Any suggestion? It seems a bit silly to just copy the bash file to .bat. And I ran it is GitBash so it should know bash (but it doesn't, apparently)

Yes, emitting this may be a bug in pixi.

Conda / conda-forge / pixi currently use bash .sh for Unix and .bat for Windows by default, although there is WIP for a unified shell script.

Thanks Matt! Shall we then postpone this PR until the pixi bat/bash issue is resolved (possibly by moving to a unified shell script)?

[thewtex]

@N-Dekker yes, we could postpone

OK, I'll leave it open for a few weeks to see if someone comes with a solution to the bash/bat shell script problem. Otherwise I'll close it, considering the PR "postponed". Unless someone else has closed it in the mean time 😸

Anyway, it was a good leaning experience for me to make my first pixi.lock fine 😃 Thanks Matt!
