Add UTM parameters to the registration URL so we can track the source.

@sdserranog We currently use Cloudflare to create the shortcut api.arcade.dev/signup. It is done with a Page Rule here: https://dash.cloudflare.com/8eea19ea3af73afba5044637e55cd204/arcade.dev/rules/page-rules/form

I would like to find a way to keep the api.arcade.dev/signup shortcut, but allow these UTM params to be appended to it. I'm not sure if that already works with the page rule as-is, can you test it?

If that doesn't work with page rules out of the box, then an alternative is creating a Worker Route with a small worker that has the biz logic to rewrite the URL as a 302 but append incoming query params to it.

Thanks for getting this working @sdserranog!
