Run repository-ydb-v2 integration tests regularly

[nvamelichev]

• Ensure that every integration test in repository-ydb-v2 uses YDB TestContainers
• Add GitHub action that runs mvn [...std args] -Pintegration-test -Plombok clean verify on commit
• Ensure that the new GitHub action works properly
• Make GitHub action run regularly and/or on every commit

Maybe we should run this test on every PR? It isn't look like long-time tests even over docker

If integration tests take less than a couple of minutes to run, sure 👍

YDB Repository integration tests now use TestContainers and run on every commit, along with the usual unit tests, e.g.:
