Add output "ticketNumber"

[koppor]

Summary

Fixes #57

Now the action can be used to output the determined ticket number. One can also configure outputOnly to use only the determination of the ticket number.

Example use:

      - name: Determine issue number
        id: get_issue_number
        uses: koppor/ticket-check-action@add-output
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          ticketLink: 'https://github.com/:owner/:repo/issues/%ticketNumber%'
          ticketPrefix: '#'
          titleRegex: '^#(?<ticketNumber>\d+)'
          branchRegex: '^(?<ticketNumber>\d+)'
          bodyRegex: '#(?<ticketNumber>\d+)'
          bodyURLRegex: 'http(s?):\/\/(github.com)(\/:owner)(\/:repo)(\/issues)\/(?<ticketNumber>\d+)'
          outputOnly: true
      - name: Move issue to "Backlog"
        uses: m7kvqbe1/github-action-move-issues/@add-issue-parameter
        with:
          github-token: ${{ secrets.GH_TOKEN_ACTION_MOVE_ISSUE }}
          project-url: "https://github.com/users/koppor/projects/7"
          target-labels: "📍 Assigned"
          target-column: "Backlog"
          ignored-columns: ""
          default-column: "Backlog"
          issue-number: ${{ steps.get_issue_number.outputs.ticketNumber }}
          skip-if-not-in-project: true
