examples: multi-tenant add all params to tenantsArrayField

[bratvanov]

What?

After updating to Payload v3.20.0, my app derived from the multi-tenant example started throwing an error:

InvalidFieldRelationship: Field Tenant has invalid relationship 'undefined'.

A quick search revealed a comment by @janbiasi which pointed out the issue – a missing tenantsCollectionSlug in tenantsArrayField defined in the Users collection.

Fixes #10874

This commit which landed in Payload v3.21.0 changed the params of the tenantsArrayField, once again making the multi-tenant example outdated and throwing an error:

TypeError: Cannot read properties of undefined (reading 'includes')

I've pushed another commit to this PR which adds the new params to the multi-tenant example.

@bratvanov thank you for this! I really do not want this issue to fall onto the example though. The plugin should be using default values for these arguments. I opened this PR that does just that. Let me know what you think. Should we keep your PR? I don't want to overwhelm users with arguments if they don't need them.

@JarrodMFlesch I completely agree, your approach with default values in the plugin is more elegant, thank you for implementing it! I'll close this PR in favor of #11030.
