feat!: Implement Enterprise SCIM - EnterpriseService.ListProvisionedSCIMUsers

[elminster-aom]

BREAKING CHANGE: ListProvisionedSCIMGroupsEnterpriseOptions optional fields are now pointers.

Related with #3813

Summary

From REST API endpoints for Enterprise SCIM docs, implements:

• List SCIM provisioned identities for an enterprise, GET /scim/v2/enterprises/{enterprise}/Groups

Other changes

• Fix Enterprise.ListProvisionedSCIMGroups Accept header, set it to application/scim+json
• Correct Enterprise.ListProvisionedSCIMGroups unti test function name

[elminster-aom]

Found an incoherence about the Accept header. While the document states for all endpoints:

Headers
accept string
Setting to application/vnd.github+json is recommended.

Their example endpoints use different values. For example on GET .../Users: -H "Accept: application/scim+json"

Reported to GitHub support and they confirmed that:

The correct header is Accept: application/scim+json.

Fix here for EnterpriseService.ListProvisionedSCIMGroups

TODO

Fix for SCIMService endpoints too.
