chore(deps): Update dependencies and Docker images

[reneleonhardt]

Issue description

• Update dependencies, plugins and Maven (Wrapper)
• Update Docker images and switch to alpine
• Use SCRAM authentication instead of md5 (default since Postgres 14)
• Testcontainers only use JUnit Jupiter
• Run tests with UTF-8 encoding and disable logging
• Fix test.bash
• Let Dependabot update Maven dependencies and GitHub Actions weekly
• Build with JDK 17 for Java 8

Additional context

There were no tests for PgPool, I just updated the Docker image.

Thanks for looking into this. The way the changes are arranged makes it impossible to backport these to the currently maintained version 1.0.x. A lot of these changes make sense and are interesting though.

I can rebase onto main if that's what you mean by backport 😅
