[WIP] Complete Zod migration for m365group-set command

[Copilot]

Coding agent has begun work on Complete Zod migration for m365group-set command and will replace this description as work progresses.

See problem context

Update all command.action calls in the m365group-set.spec.ts file to use the commandOptionsSchema.parse() pattern, following the Zod migration pattern established in the reference commits.

The pattern to follow is:

• Replace { options: { ... } } with { options: commandOptionsSchema.parse({ ... }) }
• For assert.rejects calls, keep the as any casting when needed

There are approximately 20+ action calls in the spec file that need this update.
