PRO-16379: Parse id from branch and accept lower case in project name

[BanarJoomPro]

Added parsing of the Jira ID from the branch name, not only from the PR title:

 if (typeof pr.head?.ref === 'string') {
    extractIssueNumbers(pr.head.ref).map((id) => ids.add(id));
  }

const ISSUE_PATTERN_RE = /(?<![a-zA-Z0-9])[A-Z][A-Z0-9]{1,}-\d+(?![a-zA-Z0-9])/gi;
i (case-insensitive) - added to support Branch and PR names in lower case

result.add(issue.toUpperCase()));
issue.toUpperCase - required to avoid accidentally getting duplicates from the same number with different letter casing
