Thanks for the pull request.

The PPA was added to instructions at the point where tsserver started requiring nodejs that was newer than what existed in Ubuntu at the time.
As a general policy, the instructions should work out-of-the-box for the latest Ubuntu LTS.

I think we should wait for ubuntu 24.04 to be released this week and then start with some more general cleanup.

But the packages you mentioned are now available in Ubuntu's own repositories. Why would they remove them in a newer Ubuntu version? If they were going to remove it in a newer version, then why did they add it now?

[bstaletic]

Checked and the new ubuntu does have a new enough nodejs. We can safely merge this.

This was run a while ago, so mergify config does not match.
Merging manually.
