Renamed some framework IDs (non-functional)

[eddie-knight]

This is related to, but not dependent on or blocking #349

I noticed that some of the framework names could have clearer IDs, and since we aren't restricted by length, I've proposed:

• ScCrd -> Scorecard
• OCRE -> OpenCRE
• OC -> ISO-18974

For review simplicity, I'd like to do this prior to migrating to the full use of metadata.yaml in a subsequent PR

Looks like a good change to me. We could call 18974 iso18974 if that feels a little clearer, but I'm fine either way.

I built it in my fork and everything worked as expected.

I find ISO-18974 provides more clarity than simply 18974. The remaining changes definitely add clarity though.

Whoops! Fixing a conflict invalidated previous reviews.
