GET/HEAD requests: do not attach query parameter if value is undefined

[gr2m]

Example

const requestOptions = endpoint("GET /repos/{owner}/{repo}/contents/{path}", {
  owner: "owner",
  repo: "repo",
  path: "path/to/file.txt",
  ref: undefined,
});

requestOptions.url is now "https://api.github.com/repos/owner/repo/contents/path%2Fto%2Ffile.txt?ref=undefined", but should be just "https://api.github.com/repos/owner/repo/contents/path%2Fto%2Ffile.txt"

I'd appreciate a pull request if anyone would like to work on this. You can start out by creating a pull request with a failing test reproducing the above behavior. The test will go into test/endpoint.test.ts.
