docs: add product id template

Now that we are asking users to report unknown product ids, it will be useful to have
a specific template to guide them into giving the correct information required to build
out the product sections of configs.

So far users have used the general bug template to report the log message as a bug, or the
new device template, which asks them to look up information that should not be needed.

+        This should be from the HA log message that prompted you to make this report, though if the cloud product id is different than the local product id, it can also be from the message when adding a new device using the cloud assisted setup flow.
