option to make -DskipTests optional

[mbeaudry-coveo]

When this plugin executes the deploy maven target, it uses the -DskipTests option as shown here:

    try {
        await exec(
          command,
          [
              ...cleanOption,
              ...mavenTarget.split(' '),
              ...settingsOption(settingsPath),
              ...debugOption,
              '--batch-mode',
              '--no-transfer-progress',
              '-DskipTests'  // <=======
          ]
        );

Because this option is used, we are forced to run mvn twice in our CI:

1. We first run mvn verify to make sure that all our tests pass. This is necessary to ensure that the release will be ok.
2. Then, mvn is called a second time indirectly when we call npx semantic-release.

In some cases, calling maven twice can add significant delays to a build. Ideally, it would be possible to only call npx semantic-release to both run the tests and deploy the pacakge.

So what do you think of adding an option so that -DskipTests can be added or not to the mvn deploy invocation? This would shave many minutes for several projects that I am working on.

Thanks for considering this change and for maintaining the tool 👍
