Hi there,

I find there is one check failed, saying file's SHA on x86_windows's is incorrect.

Error: While reading versions for port transwarp from file: C:\a\1\s\versions\t-\transwarp.json
       File declares version `2.2.2` with SHA: a21d15430c4c31ab2e8f597191578b33862ff234
       But local port with the same verion has a different SHA: 532341b073fc648d89f9430488535076bbe34e05
       Please update the port's version fields and then run:
vcpkg x-add-version transwarp

I did run ./vcpkg x-add-version --all before submitting the PR, do I still need to run vcpkg x-add-version transwarp for it?
