Add MinGW support to installer script

[Copilot]

The installer script fails on MinGW/MinTTY with a 404 error because uname returns MINGW64_NT-10.0-19045 (or similar), which the script doesn't recognize. It attempts to download a non-existent croc_v10.3.1_MINGW64_NT-10.0-19045-64bit.tar.gz instead of the Windows binary.

Changes

• Map MINGW* OS strings to Windows in the OS detection case statement
• Set download extension to zip for MinGW environments

case "${croc_os}" in
   "Darwin" ) croc_os="macOS";;
  *"BusyBox"* ) croc_os="Linux";;
  "MINGW"* ) croc_os="Windows";
              croc_dl_ext="zip";;
  "CYGWIN"* ) croc_os="Windows";
              croc_dl_ext="zip";
              print_message "== Cygwin is currently unsupported." "error";
              exit 1;;
esac

MinGW users can now install using curl https://getcroc.schollz.com | bash, which will correctly download croc_v10.3.1_Windows-64bit.zip.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/schollz/croc/releases/tags/v10.3.1
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_description>### What happened?

The OS is detected as MINGW64_NT-10.0-19045, and tries to download croc_v10.3.1_MINGW64_NT-10.0-19045-64bit.tar.gz from releases, which simply doesn't exist and download fails.

What did you expect to happen?

The script should account for being in MINTTY, and download the windows file and follow windows installation instructions.

Steps to reproduce

1. Install MINGW
2. Launch MinTTY (MINGW64 bash terminal)
3. Run curl https://getcroc.schollz.com | bash

croc version

None

Operating System

Windows

OS Version

Windows 10 64bit
