New source: airbyte-native Zendesk Support

[sherifnada]

As part of the migration away from Singer based connectors in #3582 we want to rewrite this connector using the Airbyte CDK. The new connector should take the following config options:

• start_date
• subdomain
• auth method (oneOf)
  • if the auth method is "API Token":
    • api_token
    • email
  • in the future we will support "oauth" as an auth method, so for now the "oneOf" will have just one branch. See the file source for an example of a oneOf configuration in spec.json.

It should also support the same streams supported by the Zendesk Support (Singer) tap, but we should do a scoping of the available streams to understand how the implementation should proceed.

Also the new source should cover the issue outlined in #4373 .

Once this issue is resolved we should prioritize #4373
