This package wraps conventional-changelog-conventionalcommits and configures the header to start with a Jira ticket prefix. The intended use case is with @jscutlery/semver since that is currently the only way of updating the header pattern.
Correct messages according to this pattern are:
JIRA-1234 feat(package) some change
So the ticket number has to come first followed by the normal conventional commit pattern. With the one exception that the colon after the type is optional.
