Add Vimeo as a provider

Add Vimeo as a provider so as to take advantage of the oEmbed endpoint.

Vimeo has started to ban IP blocks from popular providers  (DigitalOcean, Vultr, Google Cloud) due to malicious behaviour from some IPs but subsequently affecting legitimate use cases. The ban results in 403 error codes when attempting to embed URLs using the standard "webpage" adapter, however oEmbed is unaffected.
