Publish to OpenVSX

Original issue on GitLab: https://gitlab.com/inko-lang/vscode/-/issues/1

This is just a tiny feature request. Forks of vscode don't use the official Microsoft marketplace for extensions, but instead use Open VXS.

The extension should probably also be published there, to reach more people. (This should only require making an account and sending it there, no changes to the actually extension.)

I don't know for how many people this is relevant, but some on some linux distributions the default package of vs code uses Open VSX.

FYI, this is how I did pushing to Open VXS and the MS one 2 years ago: https://github.com/roetlich/pointless-syntax-highlighting-vscode/blob/master/.github/workflows/publish.yaml

Not sure if this still works, but probably 😅
Still requires regenerating the MS token every now and then, but at least openvsx should just work automatically. If you want to I can look into it, but I can't create the token.

@roetlich Do you know if it's possible to automate the token regeneration process? If so that would be pretty neat, and we could automate the whole process, but my guess is that this isn't possible 😞
