Forks can't pass CI Github Actions on their PR

[somaweb3]

Contributors must be able to push their to the website repo and open the PR there in order for the Deploy Preview action to succeed.

From @evandrosaturnino :

It doesn't seem safe to me build a preview utilizing threshold domain from an external fork trying to merge with main repo, so that's why I believe that's a permission issue, the cloudflare preview is integrated to the main repo, not yours, so that's why I assume it's unrecognizing this INPUT_SERVICE_KEY  into your PRs repo.
