Explore Circle-CI electron-builder image consolidation

[ixje]

There currently are 2 docker images used. 1 for Linux and 1 for Windows.

neon-wallet/.circleci/config.yml

Lines 4 to 16 in 714af66

	container_config: &container_config
	docker:
	- image: electronuserland/builder:wine-chrome-05.21
	environment:

The Windows image has no tagged version other than latest which could become a problem at some point (i.e. neon-wallet currently doesn't work with node 16.x and that image might upgrade node from 14.17.0 to 16.x). It is unclear why this setup exists. The task is to explorer the differences between the 2 images and see if both platforms can use the same image.
