To handle the rebranding of the GE plugin, this PR updates the inject-develocity init script
to apply the `com.gradle.develocity` plugin if `3.17+` version of the plugin is requested.
This PR changes the behavior such that task input files are captured
when the environment variable is explicitly specified and for the cases
when the plugin is not applied.
