Try to detect default GitHub branch

[joaomoreno]

More and more people are changing their default branch from master to main. It would be great if VSCE could detect this and do right right thing when publishing an extension instead of assuming master.

My suggestion is:

$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/master

And it will work not only in GitHub.

Another option is to use vsce publish --baseImagesUrl <URL to your repo>. This is how I fixed it.

IMO, it would be nice if this could be a setting in the package.json file. Like:

vsce: {
  "defaultBranch": "main"
}
