[Gradle Tutorials] Add VS Code section to main Gradle guide

[JadeCheah]

Current

• The IntelliJ IDEA guide’s “Importing a Gradle project” covers only importing and configuration (Gradle plugin, JVM, JDK).
• VS Code guide’s “Importing a Gradle project” also includes running tasks, testing, and editing build.gradle files.
• main Gradle section already provides full tutorials on installation, running tasks, and managing dependencies, but only for IntelliJ and terminal users, not VS Code.

Problem

• This creates inconsistency and overlap:
  • VS Code’s page repeats general Gradle content found in the main tutorial.
  • IntelliJ’s focuses only on importing.
  • The main Gradle section lacks VS Code coverage.
• Readers may be unsure where to find Gradle usage information under the IDE guides or under the Gradle section.

Proposed Solution

1. Option 1: Move VS Code Gradle usage content to the main Gradle tutorial and add a “VS Code” tab there. Keep both IDE guides focused on importing.
2. Option 2: Expand both IDE guides to cover the full Gradle workflow for consistency.

@JadeCheah I'm OK with option 1
