EXT-313

Checklist before requesting a review (skip if just adding/editing APIs & templates)

• I added tests, otherwise the reason is:
• External API requests have retries
• Pagination is used where appropriate
• The built in nango.paginate call is used instead of a while (true) loop
• Third party requests are NOT parallelized (this can cause issues with rate limits)
• If a sync requires metadata the nango.yaml has auto_start: false
• If the sync is a full sync then track_deletes: true is set
• I followed the best practices and guidelines from the Writing Integration Scripts doc

EXT-313 Gorgias user provisioning

[khaliqgant]

Let's just make this User instead of GorgiasUser. This should change in the sync and the actions

[viictoo]

I used a GorgiasUser type instead of User because User is already being used in a different synchronization with a different type.

    User:
        id: number
        firstname: string
        lastname: string
        meta: object | null
    ```
