fix: add JuliaProject.toml, docker-compose suffixed variants, consolidate tests

- Add JuliaProject.toml to julia manifest detection (matches
  dependabot-core's file_fetcher regex)
- Add common docker-compose suffixed variants (dev, ci, prod, test,
  override) to match dependabot-core's broader regex support
- Consolidate docker, maven, gradle individual tests into the
  parametric ecosystem test to stay under pylint's 1000-line limit
- Fix indentation issue in test loop body
