Is your feature request related to a problem? Please describe.
I have an environment where there are TLS problems dealing with proxies and other variables. This prevents me from using the tool at all for installing zig or zls.

Describe the solution you'd like
Some other languages and tools allow for TLS verification to be disabled via an argument or an environment variable.

Example in Golang

tr := &http.Transport{
    TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
}

Describe alternatives you've considered

There really aren't any other alternatives other than installing and managing Zig myself manually.
