feat: publish beta and development tags on npm

[jsjoeio]

Changes

This PR makes two major changes to how we release the npm package.

PRs are published with PR number and commit

When a PR is opened into main, we publish the npm package under a tag with the PR number. For example, you could install code-server based on #4768 and the commit 1a44d9b by running:

yarn global add code-server@4768

If you needed to install a previous commit on the same PR, you can get more specific and run this:

yarn global add code-server@4768-1a44d9b8839642b048fe5816946208a9e910f132

This allows developers to test PR changes in a production setting by installing code-server locally with a specific tag.

Merges into main are published on npm under the beta tag

Anytime a PR is merged into the main branch, it triggers a GitHub Actions workflow to publish those changes as an npm package tagged with beta.

This allows anyone using code-server to use the bleeding edge version by running yarn global add code-server@beta. The benefit of this is allowing both users and maintainers to test new features before a release.

Testing

You can test the development version from this PR here. To install locally run:

yarn add code-server@4769

Questions

Is there a limit to how often we can publish to npm?

According to S/O, no:

there is no restriction on how often a package can be published.

Fixes #4744

This works! See published version here: https://www.npmjs.com/package/code-server/v/4.0.1-4769-ad7b23cfe6ffd72914e34781ef7721b129a23040

I would like a second opinion on the implementation. There are ways we can refactor this but I am unsure if it's necessary.
