Atlassian announced that it will no longer provide information about
comments along with their "issue" type event payloads for Jira. So
we must now update the Jira integration to appropriately respond to
"comment" type events (the reason why we didn't do this before was
that initially, the "comment" type event payloads didn't contain
sufficient information about their issues, but this payload has
since been improved).
Note: This commit does *not* remove support for the older "issue"
type event payloads where information about comments was included.
This way we can maintain compatibility with old self-hosted versions
of self hosted Jira (2016 and before).

Fixes#13012
comment_created payloads may not contain the required issue data
to format a useful notification, therefore, it is better to handle
issue comments through issue_updated events (which we already do).
Fixes: #11995.
