Notify uploaders via email when their WordPress.tv video is accepted

[rollybueno]

Currently, uploaders who submit videos to WordPress.tv receive no notification when their video is approved and published. This can lead to uncertainty about the status of their submission.

Proposed Enhancement:
Introduce an automated notification system that sends an email to the uploader once their video is approved and published. The email should include:

• Confirmation of approval
• A link to the published video
• Optionally, thanks and guidelines for sharing

Benefits:

• Improves communication and transparency with contributors
• Encourages engagement and sharing of published content
• Aligns with WordPress’s community values by acknowledging contributions

For this to happen, the upload form should have additional fields:

• Optin/Optout option: Notify me when my video is approved
• Email: Email field

I'm not quite sure how possible to pull email address through WP.org profile data, so having an email field is better option
