Solve the problem of not specifying the html option in TypeScript #187

This Pull Request (PR) is intended to resolve a bug identified in Issue #187.

Main Changes

The following updates have been made:

Modified the 'url' property in 'OpenGraphScraperOptions' to be an Optional Property.
Added an error message to be thrown earlier when both 'html' and 'url' are provided.

I could not pass all tests in my environment, probably because it depends on the location where the test is executed. I would appreciate it if you could run the test in your environment just to be sure.

The failed tests are as follows

107 passing (31s)
  6 pending
  3 failing

  1) basic
       vimeo.com should return open graph data:.

      AssertionError: expected [ { height: '720', ...(3) } ] to deeply equal [ { ...(4) }
