Build electron package on Linux with Bazel

[vitvakatu]

Pull Request Description

As of ef55bcc:

Linux app image build is working, with some differences:

• JVM build of the engine, not native image
• Engine distribution is missing data directories in projects, e.g. Examples are not available.
• Version info is not correctly reported and in Engine and AppImage metadata.
• THIRD-PARTY licensing files are missing from the distribution

Otherwise, it should be a perfectly working linux build of Enso.

Mac build works, but only unpacked (dmg image packaging is not available yet)

Windows build does not work.

Building the application

Don’t forget to pnpm install first!

Application can be build in two modes:

• pnpm exec bazel build //app/electron-client:dist — uses production .env file, versions info reported from inside the app can be incorrect. This is considered a legacy mode, and eventually we will transition out of it (with more sane defaults).
• pnpm exec bazel build --config=release //app/electron-client:dist — uses .env file that matches the NODE_ENV environment variable. The build should have correct version info in GUI. This is the inteded way of building the package.

Built application is available in bazel-bin/app/electron-client/ide-dist.

Application is broken at the moment because of recent ydoc changes, investigating.

Ydoc issue fixed

I consider this PR ready to merge. It has fewer features than we planned initially, but:

1. It is not changing anything compared to develop
2. It allows starting testing app packaging on Mac and Linux in the development environment, and also provides useful feedback for testing engine distribution in Bazel.

@Frizi, please review the code. Most comments will likely be extracted to the TODO list and addressed separately.

The current TODO list is available at #12860
