Rename environment variables according to the Keycloak documentation and adjust some values to this.

Description of the change

Applicable issues

• partially fixes Keycloak environment variable inconsistency in naming / Not matching the Keycloak documentation (anymore?) #32881

Note that I explicitly set the configFile here as of https://www.keycloak.org/docs/latest/release_notes/index.html#infinispan-default-xml-configuration-location

With Keycloak versions >= 26.1.0 this should not be necessary anymore, but is maybe still better to be explicitly set then implicitly assumed.
