This can be further improved by using dynamic imports. However, I didn't include it in this pull request, because using dynamic imports needs making getAgentDispatcher async, which changes the return type of a public method. Based on my research, this is only used in the github package, so it should be fine, but if we want to go with that, we need to have a major version bump for http-client.

This makes the loading of undici conditional by lazy loading it inside the actual function that needs the ProxyAgent.
undici is a huge library, and here it is being imported unconditionally, which results in 500KB bloat in the bundles of http-client. By requiring only what is needed and when it is needed, this issue is resolved.
