ls-remote fails inside docker container with "undefined symbol: curl_global_sslset"

I've got some code that runs fine on my local (OS X) dev machine, but when I run it inside a docker container (based off of the `node:14.14.0` image), it fails with this error:

```
/app/node_modules/dugite/git/libexec/git-core/git-remote-https: symbol lookup error: /app/node_modules/dugite/git/libexec/git-core/git-remote-https: undefined symbol: curl_global_sslset
```

This is coming from a line that's trying to run `ls-remote` on an `https://` remote URL.

Any ideas why this is happening and what we can do?
