feat(deps): make https-proxy-agent optional (#2388)

Bump https-proxy-agent to v7 and a dev dependency. This makes configuring bundlers easier to configure and removes a direct dependency of `https-proxy-agent`. BREAKING CHANGE: Configuring a proxy is done by specifying the `agent` parameter on the ConnectionOptions config. This can use be created by libraries such as `https-proxy-agent` or any that implements `http.Agent`.
