chore: upgrade JVM version from 11 to 17

This change is necessary for integrating the alchemist-graphql module,
due to the strict JVM requirement that GraphQL Kotlin needs (JVM >= 17).

See ExpediaGroup/graphql-kotlin#1638 on why
GraphQL Kotlin needs such JVM version (TL;DR this library is mainly
built for SpringBoot applications, and SpringBoot v3 requires JVM 17).
