chore(docs): Update required information for support

What does this MR do and why?

This change simplifies the troubleshooting instructions for users reporting bugs with the GitLab plugin for JetBrains IDEs (like IntelliJ).

Previously, users had to manually collect diagnostic information through multiple separate steps - gathering different types of logs, navigating to various menu options, and copying specific sections of system information.

The updated instructions now offer two approaches: an automatic method (recommended) that runs a single "Export Diagnostics Bundle" command to automatically collect all necessary information into a downloadable zip file, or a manual method for users who prefer the step-by-step approach. This streamlines the bug reporting process by reducing the number of manual steps required while still providing the same comprehensive diagnostic information needed by developers to investigate issues.
