(#422) yarn preview-upgrade improvements

[st3phhays]

Description Of Changes

This adjust the yarn preview-upgrade command to first remove the yarn.lock file in the chosen repository before upgrading choco-theme. By doing this, it ensures all dependencies are upgraded of choco-theme and not just choco-theme itself. This is desired in most cases.

Also, the CCM repository has been added to the list of configs, so that is caught when using the --all or --ccm flag on yarn commands.

Motivation and Context

This command was not properly updating dependences and needed to be fixed.

Testing

1. Pull down this branch.
2. On CCM, make sure you are on the develop branch and you have the latest changes pulled in from upstream.
3. In choco-theme, run yarn preview-upgrade 0.8.1 --ccm
4. You should see multiple things changed in the yarn.lock file in the CCM project repository. Do not commit anything, we're just checking to see that it caught "things".

This is draft due to not being really needed right now. I think this would be best to review in a few days, when some of the dependencies have been bumped by the maintainers. This will give us a better view of how it upgrade dependencies.
