Update Authorizer package to point to the latest JWT package version that supports Cognito token.

[Duslerke]

What:

• Bump Hackney.Core.Authorization's Hackney.Core.JWT dependency to latest.

Why:

• Ensure Authorization is pointing to the interface from same version of package as is the JWT version used by APIs to pass the actual implementation of referenced interface.

Notes:

• Just housekeeping to prevent developers needing to guess what's changes have been missed from JWT the next time they need to bump JWT here. The only real change since 1.72 that JWT received is PR Add cognito authentication flow token schema support. #68 . The other version in between was unintentional deployment triggered by changes to a nuget token variable name within nuget.config.
• This Authorization package only uses the ITokenFactory interface definition from JWT, not the actual implementation, so it won't get negatively affected by this bump.
