Update release instructions for Windows

[Irev-Dev]

In the releases there are install instructions for various platforms, but the windows instructions are wrong as they use linux paths e.g.

windows/amd64

# Export the sha256sum for verification.
$ export KITTYCAD_CLI_SHA256="ee4a911b6814262b4e4d83c877654715a6442d401dbd2a104ebf31e82101e024"


# Download and check the sha256sum.
$ curl -fSL "https://dl.kittycad.io/releases/cli/v0.0.9/cli-windows-amd64" -o "/usr/local/bin/kittycad" \
	&& echo "${KITTYCAD_CLI_SHA256}  /usr/local/bin/kittycad" | sha256sum -c - \
	&& chmod a+x "/usr/local/bin/kittycad"


$ echo "kittycad cli installed!"

# Run it!
$ kittycad -h

Changes probably need to be made to cli/basic.mk

Looking at our cli install action might help as it works with a Windows runner, though it still uses bash, perhaps instructions should use powershell. Also adding the cli to %PATH% would be different outside of a github action runner.
