Incredible, this typo has been here for at least 4 years undetected.

Unfortunately changing it directly like this would be a breaking change, in case anyone's using the old name. We need to:

• Add a new, correctly spelled function, like you've done here.
• Keep the old misspelled one and just have it call the new one.
• Add a deprecation warning to the old one that it will be removed in v13.
• Add a rename to the migration database so that folks can automatically update their code when migrating to v13.
• Update the internal usages of the function.

Let us know if you're still interested in fixing this with these additional steps. Thanks!

Added unregisterWorkpace to the migration database. Is this the right approach?

Nice, thank you! One suggestion then lgtm.

As the repository changed to a monorepo, I merged the main branch and made changes to core/workspace.ts.
