feat: migrate to using security context

BREAKING CHANGE: The type IRI for BBS signatures now stems from the https://w3id.org/security namespace, meaning all future signing and verifications using the signature suite will now use that namespace rather than the placeholder namespace that was being used. Note - this means verifying signatures and proofs issued with older versions of this library will not work.
