Update feedback issue template

The goal of the feedback issue template is to make it easier and provide a skeleton for opening feedback issues for specific features as done in the past, see relevant pull request in #10593.

See also [relevant discussion](https://gitpod.slack.com/archives/C01KLC5750D/p1652903673228329) (internal).

There were a few issues (see list below) opened recently using this template for general feedback which also automatically adds the feedback-issue label.

This will update the description of the template to clarify the goal of this template.
