/**
 * Automatic CI process for generating new vcpkg releases.
 * Based loosely on RealTimeChris's shell script version.
 * 
 * This updates the content of ./vcpkg directory within the DPP
 * repository on the master branch, which can then be diffed into
 * the microsoft/vcpkg master branch to build a PR for the new
 * release.
 * 
 * The procedure for this is:
 * 
 * 1) Generate various configuration files and put them into the
 *    systemwide vcpkg installation inside the CI container
 * 2) Attempt to build the package from the release tag,
 *    this will fail due to invalid SHA512 sum and return the
 *    correct SHA512 sum in the error output. Inability to get the
 *    SHA512 sum here will return nonzero from the script, failing
 *    the CI action.
 * 3) Capture the SHA512 from the error output, switch to master
 * 4) Copy the correct configuration into both the systemwide
 *    vcpkg install in the container, and into the vcpkg directory
 *    of master branch.
 * 5) Rerun the `vcpkg install` process again to verify it is working.
 *    A build failure here will return a nonzero return code from
 *    the script, failing the CI action.
