[FR] Restore win32 support, electron v21.4.3 still supports it.

[JMVS]

Homework

• [X] I took the time to write a good, descriptive issue title
• [X] I read nativefier --help and API.md, no existing option fits my needs.
• [X] I checked CATALOG.md for community suggestions & workarounds.
• [X] I searched existing issues, open & closed. Yes, my feature request is new.
• [X] I'm running the latest version. Yes, the feature I'm requesting isn't in it.

Problem statement

Nativefier 49+ have removed the win32 option because, and I quote, "The ia32 arch (a.k.a. i386 or x86/32bit) is no longer supported". I've just tested compiling using Nativefier 48.0.0.0 and Electron 21.4.3 (lastest available at the time of writing) and it works under a Windows 10 32 bit machine. This is the command I used: nativefier URL -p windows -a ia32 -e "21.4.3"

Motivation & context

I don't know how hard would be to bring back this option but I find it still useful for use in old computers that don't support 64-bit architecture.
