Stabilize link-check for Raspberry Pi Imager documentation URL

[Copilot]

The link-check workflow was failing on profile/RPI_GH_Runner.md because Lychee received a 403 Forbidden from a Raspberry Pi documentation URL. This change scopes the fix to link-check configuration so the workflow stops failing on that known environment-sensitive endpoint.

• Root cause

  • lychee rejected https://www.raspberrypi.com/documentation/computers/getting-started.html#imager-install during CI with 403 Forbidden

• Change

  • Added the exact Raspberry Pi documentation URL to .lycheeignore
  • Kept the fix aligned with existing handling for other Raspberry Pi links already treated as flaky / environment-sensitive

• Effect

  • Preserves link checking for the rest of the Markdown content
  • Removes the single known false-negative source that was breaking the link-check job

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot cloud agent settings (admins only)
