merge electron build with this repository and add it to CI

[VigneshVSV]

The electron build repository is here. No longer remember why it was created separately, most likely for testing.

First fix this issue - self signed certificates

We should provide electron desktop app with every release

Rough steps

• make sure the electron app is buildable again as the changes may be outdated, or create a new working electron packaging
• add a CI job that will automate creation of this electron app
• choco install (or similar for linux) of this entire application would be a great plus
