Description

Sometimes, especially during development and troubleshooting, it would be nice to be able to reinstall a version in a similar manner to Homebrew. In its primitive form, it could be just uninstall and install chain, but take further, it could be done transactionally, too, i.e. a failure to install won't remove the previous instance.

Contributor guide

Research direction
Explore the asdf codebase to understand the install and uninstall commands' implementations. Design a reinstall command that first backs up the current version, then runs uninstall followed by install, restoring the backup on failure. Look for existing patterns in the codebase for transaction like behavior.
