Remove relay extension from AWS Layer

we're reverting back to the older setup since the whole 'relay as AWS extension' experiment didn't really work out.
* revert port override in DSN
* remove gh action that bundles relay
* zip in place as part of `buildLambdaLayer`

part of getsentry/team-webplatform-meta#58
