Rig 0.7.0 does not work with Proxy and Internal CA Certs on MacOS

[chrisphe]

Whilst Rig 0.6.0 works perfectly on MacOS, with 0.7.0 I saw an error regarding certificate validation on MacOS:

[ERROR] Cannot download JSON: error sending request for url (https://api.r-hub.io/versions/available/macos/arm64): error trying to connect: invalid peer certificate: UnknownIssuer

I suspect that Rig is no longer making using of SSL_CERT_FILE.

This is probably because rig switched to rustls instead of openssl. I'll look into how to use the certs with rustls.

There's a couple of options - this PR seems to address this rustls/rustls-native-certs#32 Also https://github.com/rustls/rustls-native-certs

By way of update, I wanted to mention this issue is also occurring on Linux, so I would assume it exists on all platforms in 0.7.0.

Just adding another bump to this issue; my organization also requires use of Proxy and Internal CA Certs and so due to this issue we are no longer able to use Rig starting with version 0.7.0. Would be grateful to see this ability restored as it was before this latest release to allow us to stay up-to-date, and many thanks.
