Add support for zip archive type for Windows and macOS

[frsyuki]

I installed https://github.com/sqldef/sqldef-rails and ran bundle exec rake db:schema:dump today. It caused errors due to following 3 reasons:

• Etc.uname == 'arm64' is not expected. Error message:

KeyError: key not found: "arm64"

• sqldef repository is moved from k0kubun to sqldef on github. Thus GitHub made one additional redirect. Error message:

Expected 'https://github.com/k0kubun/sqldef/releases/latest/download/psqldef_darwin_arm64.zip' to return 302, but got 301:

• Binary releases are archived in zip format for windows and darwin. Error message:

Zlib::GzipFile::Error: not in gzip format

This PR fixes the errors and makes the sqldef-rails working on macOS.

Environment:

• macOS 12.7.2
• MacBook Pro, Apple M1
• Output of uname -m:

$ uname -m
arm64
$ which uname
/opt/homebrew/opt/coreutils/libexec/gnubin/uname
$ /usr/bin/uname -m
arm64
