feat(CI): Revalidate vercel data cache on areweturboyet after uploading data to KV store (#76693)
Without this, you'll have to wait up to 600 seconds after merging a manifest update and waiting for the upload CI job to run, which leads to some confusion. This should make it near-instant.
Calls the endpoint defined here: https://github.com/vercel/areweturboyet/pull/20
This needs the `TURBOYET_TOKEN` secret to be configured on the repository. (Thanks @timneutkens)
Tested by running it here: https://github.com/vercel/next.js/actions/runs/13635362971/job/38112680086
