Release windows binaries as .zip files

[SpexGuy]

zst is not a format that most windows users can decompress easily. Even 7zip, afaict the most widely installed third party decompression tool on windows, can't open them. For the windows binaries in releases to be useful, they should be released in a format that windows users can use. Preferably .zip, which can be decompressed directly from the OS's file explorer.

The zstd project does have windows executables in its releases, but it's a bit silly IMO to require users to download this oddly specific project to use ZLS.

Ditto for PR builds (and having an artifact per arch). Example and the result (Do note that the artifact size listed is "as produced", the downloaded file ends up being much smaller).

Only if you're sure that doing away with the .tar.zst files doesn't affect anything on the remote host in the "Beam to Felix" step.

We don't use any of the compressed archives we send to Felix, instead opting to use the single executables, so yep it's all good.

The 0.10.0 Release is shipping zstd compressed tarballs on all architectures.
