Merge #20095: CI: Bump vcpkg commit ID to get new msys mirror list

c83155b Bump vcpkg commit ID to get new msys mirror list (Aaron Clauson)

Pull request description:

  This fixes the appveyor CI job, see #20066.

  Currently the job fails because some of the vcpkg dependencies need to install msys2 and the hardcoded mirror in the vcpkg config is down.

  Vcpkg commit 76a7e9248fb3c57350b559966dcaa2d52a5e4458 adds new mirrors to the hardcoded list.
