fcos/release-checklist: issue template changes

GitHub now requires issue templates to contain yaml front matter and be located
in `.github/ISSUE_TEMPLATE/` to be properly detected as a template.

Add the required 'name' and 'about' fields in the yaml front matter and also add
'title' and 'labels' to assist with release checklist creation.
