Update electron artifacts to v19.0.4. Add Apple Silicon support

[IanButterworth]

This updates to electron v19.0.4 via davidanthoff/ElectronBuilder#5

I released the tarballs on my fork to test CI here. That will need changing back once CI passes and that PR is released.

Fixes #103
Fixes #104
Fixes #105

Other notable changes:

• set julia compat at 1.6 as I believe the MacOS aarch64 binaryplatform option errors on older versions
• as of electron 12.0 electronjs.org/docs/breaking-changes contextIsolation should be false to allow node to be used within the created windows
• fixed a typo for retval
• replaced the deprecated dep URIParser with URIs. Is the way I switchedescape for escapeuri ok?
• It seems like the relative path URI("file://test.html") test form was silently not showing the page on previous Electron.jl version tests. I switched it out to an absolute path

Remaining issues

I see the following upstream bug warning locally on Intel MacOS

On ubuntu CI this error is spammed

[1852:0610/024759.386335:ERROR:bus.cc(398)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")

but locally on ubuntu I don't see any errors:

I believe it's because the ubuntu runner needs GLFW

@davidanthoff I think this is looking good to me now.

If you agree and you'd like me to handle releasing davidanthoff/ElectronBuilder#5 and this PR, feel free to give me the necessary rights on the two repos

Bump 🙏

Is the way I switched escape for escapeuri ok?

Good question ;) As far as I can tell, the docs for the encoding methods in URIs.jl are wrong and I don't fully understand the logic of the design there... But if tests pass, lets go with it for now.

We have a custom, new implementation for uris in the LS (https://github.com/julia-vscode/LanguageServer.jl/tree/master/src/URIs2), at some point we'll probably move that into its own package, and at that point I'll probably switch this package here over. But no rush, URIs2 probably needs a bit more work first.
