JSON result for fastly service-version clone

[Tasteful]

In most commands we have the --json possibility to get the data out as json for future script processing. The fastly service-version clone does not have the --json output type and today either the string result need to be parsed or an extra call with fastly service-version list to find the newly created version and their version number.

👋 Thanks for opening this issue.

You're right, there are still some commands without --json flag support. I'll open an internal ticket to track this.
