bitbucket-copy-commit-reference: fix Jira integration for Bitbucket S…

…erver 8.9.*

As a follow-up to commit [1], fix Jira integration for Bitbucket Server
versions 8.9.*, where storage of Jira issue keys has changed, and now it
isn't available in a single dataset attribute.  In such cases, extract
the issue keys from links to Jira, automatically inserted into the
commit message.  Use dataset attribute with just the issue key from such
links to collect all keys into an array in method #getIssueKeys.

    8.9.*, 2024-09-06)
