Convention Changelog Conventionalcommits Jira

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
JIRA-1234 feat(package)!: breaking 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.

Append ! before the colon to mark a breaking change (triggers a major version bump with @jscutlery/semver).
