lb-mocha won't be able to pick lang from mocha config.

We have to use --lang with the command.

- Remove `timeout`, it should be aggregated from individual packages. At the moment, `packages/cli` is already setting timeout 5000ms. Signed-off-by: Miroslav Bajtoš <mbajtoss@gmail.com>

This is not ideal. I opened a PR to avoid eslint-disable-next-line, see #5925

parallel: trueto monorepo's root mocha configThis pull request supersedes #5011. I am intentionally keeping this change small and enabling parallel test execution only when the tests are executed for the entire monorepo. We can discuss further improvements after this pull request is landed. (E.g. which packages should run tests in parallel when running
npm tfrom their package directory. At the moment, users can opt into parallel execution vianpm t -- -p).Checklist
