[Requirement from Foundation]: Update Footer

The OpenJS Foundation has updated the required project footer to include the new AI Policy. In order to comply with the OpenJS Foundation requirements, we must update our footer accordingly.

This is quite a simple change.

@avivkeller do they have HTML template? So we will automate it (maybe we can open an issue to ask about this)
