[hotfix] Synchronize CI pipeline setup. This closes #78

* Synchronize CI pipeline setup

The Flink Kafka connector now tests:
- All PRs against `main` are tested against Flink `1.17.2` and `1.18.1`, instead of `1.17.1` and `1.18.0`
- The weekly run tests
-- `main` against `1.17-SNAPSHOT, `1.18-SNAPSHOT` and `1.19-SNAPSHOT` (1.19 is newly added)
-- `v3.0` against `1.17-SNAPSHOT` and `1.18-SNAPSHOT` (as was before)

* Make sure that Python tests are also run during CI runs for PRs
