Update JWT core package so the latest Token Factory supporting Cognito token gets used for Google groups auth.

[Duslerke]

What:

• Update the Hackney.Core.JWT package 2 versions up (1.72 -> 1.84 -> 1.87).

Why:

• To get the latest version of the ITokenFactory implementation that adds support for the Cognito token schema.
• The current v1.72 implementation crashes upon encountering Cognito Token due to empty groups key failing to map and leading Token.Groups to getting set as unhandled null.

Notes:

• Updating only the JWT core package without the Authorizer as after additional digging through source code I've found that Authorizer core package merely references the JWT core package's ITokenFactory interface definition, and does not do anything more with the package. The way the Google groups authentication setup works is that for any given API, it uses JWT core package to register TokenFactory instance DI, and then that gets used by the Authorizer middleware to populate its Auth filter dependencies. The rest of the JWT usage seems to be limited down to Token class to extract data like email or user name for Activity History purposes.
• Not updating the Authorizer as it seems to have additional functionality introduced apart JWT version upgrade, that would need extra testing. As it stands right now, due to the above reason, it does not need to be bumped on the APIs.
• The version 1.84 was a fake release, accidentally triggered by some house cleaning done by the cyber team.

It's the thought that counts! 😂

That which fails within a unit test is not even related to the package, or API in general. It's a step function step of a nightly process:

Test is flaky.
