Update 'Writing Transactions to a Ledger for an Un-privileged Author.md' to use Aries-VCR

[WadeBarnes]

Update the instructions in Writing Transactions to a Ledger for an Un-privileged Author to use aries-vcr.

The instructions currently use TheOrgBook which has been replaced by aries-vcr and retired.

The same basic processes apply to aries-vcr, and aries-vcr-issuer-controller.

Hi @WadeBarnes , a doubt regarding the repo : https://github.com/bcgov/aries-vcr

Does the name "Hyperledger Indy Catalyst" need to replaced by "aries-vcr" , i'm just trying to understand this.

Yes. We are far behind on updating the documentation for the repo. Hyperledger Indy Catalyst was the working title, but it had to change.

Ok, thank you @swcurran for confirming that.
