New Document Version Notification

[#1]

Description: An email alert is generated when a new proof version is created, but not for a new document version. This functionality is important.

Why this feature is important: Users who do not select proofs, such as agencies updating an asset based on feedback from the V1 Proof, should be able to upload a new version of an existing proof as a document. This action should notify the Project Owner/Team (based on their settings) that a new document version has been added.

Desired functionality: When a new document version is added, the system should notify the Project Owner/Team (based on their settings) of this update.

Current behavior: When a user adds a new version as a document, no email alert is sent. Users must either share the document directly with their point of contact or use an @mention in the updates to inform them
