CrateDB 4.8 fails to start on CI/GHA. Add test matrix?

## Problem
On the CrateDB JDBC driver project, we discovered CrateDB 4.8 no longer starts on CI/GHA. Because we think it is using `crate-java-testing` in its test harness, we also wanted to report it here.

## Evaluation
We can see this project does not include a test matrix to validate against different versions of CrateDB yet. Do you think it is a good idea to bring in such an improvement?

Comece revisando o test harness de crate-java-testing, além do crate-jdbc pull request 473 e do CrateDB issue 19116 referenciados. Determine como o CrateDB 4.8 é iniciado no CI/GHA e quais versões uma matriz de testes deve abranger; considera-se concluído quando a proposta estiver definida e o CI validar as versões selecionadas do CrateDB.
