CopyToRemote path structure on Windows

[svaraborut]

Describe what happened

The resource provider code CopyToRemote does not take in consideration the non-posix path structure in Windows, resulting in files being copied into the remote host user home ~ with names such as literally '\install.sh' or '\scripts\install.sh'.

Pulumi version v3.191.0

Sample program

Run on Windows

copy_files = command.remote.CopyToRemote(
    ...
    source=pulumi.FileArchive('./scripts/'),
    remote_path='/scripts',
    ...
)

@svaraborut in your example I'm assuming the source is Windows? Is the destination windows as well?

@corymhall the destination is Linux, Ubuntu 24 remote nodes. That is where the issues araises
