JVM client for Linea Smart Contract V6

[jpnovais]

Description

Build and publish mvn jar for Linea Rollup smart contract V6. New Class shall be called LineaRollupV6

Tasks

• Issue a mvn package of jvm-libs/linea-contracts/l1-rollup. Version shall be 6.0.0, however, it's recommended to release first with 6.0.0-rc1 until we have 100% integration test;
• Potentially adapt release jobs to support optional package classifier "build.linea:l1-rollup-contract-client:6.0.0:rc1"

Acceptance criteria

• Package is issued in mvn repository.

@jpnovais given we are using the SemVer 2.0 with M.m versioning, would this not be
build.linea:l1-rollup-contract-client:6.0:rc1

[jpnovais]

What if there is a but and you want to patch?
IMO, it should be 6.0.0:rc1, the RC1 means that it's still a work in progress and it not stable.

[thedarkjester]

Am I correct then in saying this does not align directly with the smart contract version itself, but just the client then?

Image that you release the official V6.0 (not the RC1); then you realise that there is a bug on the JAVA web3j generated wrapper, you patch it, what should the next version of that patch be?
