Broken link in README file

[matthewjnield]

The Fresh repository's README.md file includes the following in the "Getting Started" section:

"3. Link the Deno Deploy project to the main.ts file in the root of the created repository."

The URL of the link (https://deno.com/deploy/docs/projects#enabling) leads to a "Not Found" page, and it is not obvious to me what page of the Deno Deploy documentation this should now be linked to, so I am opening an issue rather than a pull request making the change.
