Update dependencies

[dnlkoch]

Description

Changelist:

• migrate to the latest version of graphql-java which is now available through spring-boot-starter-graphql
• updates spring-boot to 2.7.6
• replaces springfox with springdoc-openapi, this includes the upgrade to OpenApi V3 from OpenAPI V2
• upgrades keycloak to 19.0.3 (https://www.keycloak.org/docs/latest/release_notes/index.html#keycloak-19-0-0)

Open issues:

- some endpoints / models do not show up in swagger-ui (e.g. Application).

Migration guide

• GraphQL: if you have any entities beyond the SHOGun base entities, you need to upgrade your graphql configuration:
  https://blog.devgenius.io/graphql-with-spring-boot-starter-graphql-7b406998c0b5
• OpenAPI
  • remove the dependency com.graphql-java
  • the path to the OpenAPI document changed from /v2/api-docs to /v3/api-docs
    • update the path in your WebSecurityConfig and and wherever else it has been used
  • if any springfox configuration from shogun was overwritten: consider the migration notes from SpringFox to SpringDoc: https://springdoc.org/#migrating-from-springfox
  • if required you can customize the documentation using OpenAPI-specific annotations. For an example see https://www.baeldung.com/spring-rest-openapi-documentation#openapi-annotations
• The SinglePageAppController has been removed. If needed, it must be included inside your project.
