Error downloading packs with corporate certificate in chain

When I try to run `codeql pack download ...` I get the following error.

```
> codeql pack download codeql/javascript-queries

Package specifications to check for download: codeql/javascript-queries
A fatal error occurred: Could not create access credentials for codeql/javascript-queries.
(eventual cause: SunCertPathBuilderException "unable to find valid certification path to requested target")
```

This is on a computer that has a self signed certificate in the chain. For most of the tools I use there's a way to include these certificates with an environment variable or enable it to pick up the configuration with the certificate installed. I can't figure out a way to do that in this case though.

A lot of the examples online are specific to fixing this issue for JRE/JDK which I don't have, I'm just running the codeql mac os binary.

Thanks,
