Schema issue preventing component rendering form in AAT v1

[joe-allen-89]

Subject of the issue/enhancement/features

Originally raised during v1 testing - https://github.com/cgkineo/adapt-authoring/issues/40

When adding adapt-vimeo to a course in AAT the form is unable to render due to below required:

adapt-vimeo/schema/component.schema.json

Lines 10 to 12 in bc37c67

	"required": [
	"_media"
	],

Suggest moving required to _media itself to make the source required:

"required": [ "_source"],

Your environment

• Tested on https://v1testing.uat.kineoadapt.com/

Steps to reproduce

• Create a course
• Try to add adapt-youtube component
