Remove Unused Thumbnail Service Code

[arunshenoy99]

Proposed changes

This service will be deprecated soon, and since this code is not currently being used anywhere, we do not want to risk its usage in the future. If this is required, we will need to write new code to use the Cloudflare website capture worker.
