[WIP] Migrate to vscode-test module

[emtei]

Resolves #1430

I am still working on this, PR opened just to be able to test if CI builds are fine.
Still to do:

• investigate warning [email protected]: The engine "vscode" appears to be invalid. warning
• fix nvm is not compatible with the "npm_config_prefix" environment variable: currently set to "/usr/local" when running CI build

[IllusionMH]

The engine "vscode" appears to be invalid. This is yarn warning that I haven't found a way to suppress.

VSCode uses "engines" > "vscode" entry from package.json to check for minimum allowed version for extension. Which is required according to docs

Maybe these link will be helpful for you
yarnpkg/yarn#1102
yarnpkg/rfcs#69

Checks are performed in this file and looks like there is no way to ignore vscode in engines checks with configuration. Only --ignore-engines flag during installation which will disable all engine checks
