Support: update diagnose errors workflow
This MR reworks the majority of this workflow and organizes the information for better readability.
- Added screenshot to show what a linked Sentry issue looks like
- Added information on assigning labels other than bug to created issues
- Added many new headers to expand the ToC for ease of browsing
- Replaced the Sentry URL search example with a
user.id:one as the former is much less reliable
- Added screenshot showing how to select a specific Sentry issue through the events tab.
