Add in type & source to collections

[davidcba1]

What does this PR do?

Adds in a couple of more types to the template for requirements.yml to allow collections to be source from an internal url (eg .tar.gz file)

How should this be tested?

Configure a collection to point to a file directly, rather than a galaxy API eg (Mainly used for internal repos like artifactory etc)

collections: 
 - name community.general
   type: url
   source: https://galaxy.ansible.com/download/community-general-6.2.0.tar.gz

Is there a relevant Issue open for this?

I've tested this by specifying a collection with a type of URL and a https URL to a .tar.gz file and it worked as expected.

I am approving this, its a good addition.

However in the future a test to ee_utilities/.github/tests/ee_builder.yaml. I'll be following up with another PR with this.
