Disable Develocity integration by default (#993)

Configuring Develocity build scan to publish additional details breaks Gradle project isolation.

This change introduces a new property, `com.gradleup.shadow.enableDevelocityIntegration`, which defaults to false. However, it allows users to set it to true to continue using Develocity integration.
