chore: drop intention to add the share tool Expose.

- Dropping the intention to add Expose as a share tool because it just doesn't work. Can't even add the auth token without triggering cURL errors about a SSL certificate problem.

There seems to be loads of github issues related to some kind of SSL problem, with no real solution. Expose also lacks complete documentation for the CLI.

- Remove TODO for add `share-tool` command as completed.

- Changed the TODO to "Add support for other share tools" and removed some open source client links as they are no good.
