[Modules] Uplifted ADF module to support managed Private endpoints

[ahmadabdalla]

Closes #1720

Description

• Added support for a new child module for managed private endpoints for ADF
• Updated the pester test that inspects a private endpoint resource type to exclude managed private endpoints. The reason is that we are searching for the word 'privateEndpoints' using a like statement, which can conflict with 'managedPrivateEndpoints', thus marking it as the same for API versions.
