Added support for using Gradle wrapper scripts

Description of changes: Added support for using Gradle wrapper scripts AKA "./gradlew"

Why is this change necessary: Gradle wrappers enforce that a build uses the proper version of Gradle. Without this change components will be built with the system's Gradle command which may be the wrong version.

How was this change tested: I built a component locally with it

Additional tests should be added to make sure that ./gradlew is called instead of gradle when using this configuration.

Thank you for your contribution. PR looks good to me. But to proceed further, you need to make the following changes -

1. Update the commit messages to match the conventional commits format for the GitHub workflow checks to pass. You can also refer to the previous commits of this repository.

2. Add relevant unit tests and integration tests to maintain the code coverage of the repository so the codecov can pass.

3. Once you're done with 1 and 2, one of the Greengrass engineers will add UATs (mainly test data) for the same.

Also feel free to link this issue https://github.com/aws-greengrass/aws-greengrass-gdk-cli/issues/84 in your PR that you're addressing this. Let us know if you need more information.
