Remove HTTP calls from `ce_ee_vue_templates` Danger rule
What does this MR do?
Before we had a single codebase, this Danger rule had to make an HTTP call to check for a file's existence because the rule could be executed from either the CE repo or the EE repo.
Now that we are on a single codebase, we no longer need this HTTP call - we can just look at the files we have checked out locally.
This MR removes the HTTP call and replaces it with a local file lookup.
Closes #28218 (closed)
