fix: release/v12.0.0 fixes (#199)

1. Updated Settlement Models on "MojaloopHub_Setup" collection:
   - Removed "DEFERREDNETUSD" which is not valid
   - Updated "DEFERREDNET" to use the env `{{currency}}` variable.
2. Fixed "OSS-CGS-New-Deployment-FSP-Setup" collection name:
   - Changed "OSS-CGS-New-Deployment-FSP-Setup Copy 2" collection name to "OSS-CGS-New-Deployment-FSP-Setup"
3. Added helper scripts to run CGS onboarding and golden-path
4. Added OAuth Bearer Tokens for transactionRequests and authorizations tests
5. Removed Health endpoints tests as these are generally not "publically exposed"
6. Fixes to API version assertions for 1.0 & 1.1 using generic regex match: mojaloop/project#2054
7. Updated error codes for transaction-request tests
8. Added branching logic in transaction-request tests for the WSO2_OAUTH_ENABLED flag
   - HTTP Response code will be 403 instead of 400 when calling WSO2 without AUTH headers. 
   - FSPIOP Error code will be 3101 instead of 3202 when calling WSO2 without a Content-type header. WSO2 injects a Content-header if not provided in the initial request.
