feat(zapier-scim): ext 290/zapier user provisioning

[viictoo]

Describe your changes

• This PR adds support for user provisioning with the Zapier SCIM provider, including user creation, disabling, and synchronization actions

Issue ticket number and link

EXT-290

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

• I added tests, otherwise the reason is: API is limited to enterprise accounts
• 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-290 Zapier user provisioning

This should just be zapier and not zapier-scim and use the

    baseUrlOverride: "https://zapier.com/scim/v2",

since the API setup is the same. The description for the actions and syncs should mention that this is enterprise only as well.

Since this is actually SCIM it is not all that useful as a public template so closing.
