Error when more than 30 URLs are purged

Hello!  This is a neat GitHub action.  I've just made my repo dump the full list of files uploaded into this action's parameter, and it seems that Cloudflare have introduced a cap of 30 URLs per request.  In theory it should be possible to page the list of URLs into batches of 30 and purge those one at a time.  I don't know enough Bash to be able to do that though.  Thanks!
