@PhoebeHui any idea why the checks failed?
I was checking the outputs and I can't understand what caused it

@strega-nil-ms, could you please take a look? the format.diff suggest to update to original change.

The "source of truth" for documentation is stored in the helper: https://github.com/Microsoft/vcpkg/blob/master/scripts/cmake/vcpkg_from_github.cmake. We generate the .md file from the helper file using https://github.com/microsoft/vcpkg/blob/master/docs/regenerate.ps1.

You can either make the change in both places, or just make the change in the .cmake file an re-run regenerate.ps1

@ras0219 thanks!

@ras0219 @PhoebeHui looks like it's done!

The PR failures in Linux and Windows are download failures for ncurses and libsbml respectively.

[PhoebeHui]

The failures on realsense2:x64-osx would be addressed by PR #18202. I would rerun the CI test after the PR merged.

We may delay merging this change since it touches vcpkg_from_github.cmake and therefore the package hashes of most packages, but thanks for the PR!
