There are still several places in the docs
which do not properly use Hyperledger Fabric
when referring to Hyperledger Fabric.

While this change covers a lot of files, it
simply changes all reference to
Hyperledger Fabric or provides a minor rewrite
to avoid using the terms at all.

As part of this, also addressed
- FAB-5014
- FAB-5139
- Changed docker to Docker as appropriate
- Other minor cleanups since this included most of the docs
