Multiple Org Install

[Keyrxng]

Right now it's only possible to update one org config at a time so we should consider adding logic for pushing to multiple orgs which would be a great QOL improvement for those with multiple installs to tend to (like we do)

1. Present the choice within the orgSelector to enable multi-select
2. Present the choice just before push via a notification something like Are you sure you want to push to Ubiquity? "continue" | "push to more" | "cancel"

Without this feature, we'd need to run the UI flow 4 times to update one plugin which is not ideal.

• We might need to have the user confirm which org config to use to fill in existing values. We could do this simply by using selectedOrgs[0] or making it a specific interaction to choose.
• If selecting a template like minimal or full_defaults, I'd assume we'd overwrite their entire existing config in all orgs if there is one, as we could end up with duplicate plugins otherwise
• repo and file creation for all selected orgs should be covered too
