Failure to run with Docker because of different Java Runtime version

[nichtich]

I've build the jar file with gradle and get the follwoing error message when running with Docker:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/semantics/apigateway/APIGatewayApplication has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0

I suppose the local Java version (openjdk 21.0.6) and the Java listed in Dockerfile (17?) must match.

Yes you need to match both of them to java 17.

I opened another issue, to make the dev processus more easier #72

fixed in #93, no more needed to build locally
