Reverts jenkinsci/docker-agent#816

This PR removes the Windows Server Core version pinning so we can use its last image version published today as base instead of the one from April 2024.

From https://github.com/microsoft/Windows-Containers/issues/493#issuecomment-2219090926:

The updated images released as part of the July 2024 security update today include the fix for this issue.

Confirmed by building this from another host than Windows:

# OK with docker buildx build --platform windows/amd64 -t test .
FROM --platform=windows/amd64 mcr.microsoft.com/windows/servercore:ltsc2019 AS latest
COPY README.md README.md
