releasing: Add template for major releases (#9596)

* releasing: Add template for major releases

With pytest 6.0.0, we still used a manual releasing workflow (at least if I
remember correctly), and apparently we never wrote a release announcement
template for major releases. Instead, the minor release template claimed that
the release would contain "breaking changes", which doesn't seem reasonable.
Thus, this adds a new major template based on the former minor template, and
adjusts the latter to only mention fixes and new features instead.

* Update scripts/release.minor.rst
