Switch from JDK to JRE in docker images

[ViliusS]

Eclipse Temurin JDK images are really big.

I assume that JRE is enough to run Axon Server, so in order to lower space requirements and possible attack surface I propose to switch those images from JDK to JRE. JRE images are twice smaller.

Or ideally switch to Eclipse-Temurin JRE alpine images which are even smaller than default ubuntu ones.
