Add v2 gateway support

[dhelms-bw]

Proposed changes

This adds support for canary deploys with using websockets under AWS V2 API Gateways. API Gateway V2 resources with lambdas use integration resources which must be updated to execute the aliased version of a lambda during a deploy. Similarly, authenticators must also be updated to use the aliased lambda to prevent execution permissions issues.

After seeing some additional alias permission issues brought in serverless 1.60.2 reported in #71, I'm going to test this on the latest serverless and report back if this PR holds up.
