Review issues for event-subscription-template.yaml

[rartych]

Problem description
Issues indicated with r2.2 review:

• Release 2.2 #388 (comment)
  • line 19: should this URL be adapted to point to the API repository of the API using the template ?
    maybe it was discussed already.
• Release 2.2 #388 (comment)
  • line 528: the link should be relative to the release, or could be changed to textual reference without an actual link.

Expected behavior
Agreed corrections need to be applied to the file before public release.

Some feedback:

• First comment: yep it is a placeholder that is replace when this template is used for a given API design and therefore the value is replaced. Maybe adding a note in the template to mention that
• Second comment: Agree to make a reference with relative link so as in that way it will refer the status reached in a specific release

For the first point agreed with @PedroDiez - we can add a note in the documentation part
For the second point I'm fine with the solution proposed by Pedro or to simply remove the link to the design guideline (but of course keeping in the text the reference to the guideline).
