Windows build is failing with trust issues

[phlax]

The windows build is consistently failing with the following:

error: perl-File-Listing: signature from "David Macek <[email protected]>" is unknown trust

and related errors.

there are some discussions about this:

• https://github.com/msys2/MSYS2-packages/issues/2343
• https://stackoverflow.com/questions/68669920/invalid-pgp-signature-when-updating-packages-in-msys2-despite-fixes/70088371#70088371

as this only started to happen in the last day or two its not clear if its transient or something changed and we need to clear some keys or somesuch

This is typical of a new signatory to the package collection, and requires a bump in the base msys2 package provisioned in our build_windows_toolchain.ps1 script. Patch incoming.

closing as we dont officially support windows any longer
