Add new build parameter: "defaultExclusion"

This commit introduces a new build parameter, "defaultExclusion," within the build properties of the plugin. The current behavior of the plugin is to build a Docker archive with default exclusion rules, which exclude hidden files. However, the Docker CLI includes hidden files by default.

With the addition of the "defaultExclusion" parameter, users can now control whether hidden files should be excluded during the Docker archive build process. This parameter provides flexibility and allows users to align the plugin's behavior with their specific requirements.
