🌟 What does this PR do?

Fix YouTrack integration for single issue pages: #2319

• Updated selector for reporter info to be more generic (span element was changed to div on YouTrack).
• Modified issue ID selector to target the anchor element directly (span element was removed on YouTrack).
• Removed unnecessary console.log statement.

Demo after fix

🐛 Recommendations for testing

All changes should be tested across Chrome and Firefox.

The Toggl button should be tested on the YouTrack issue page.
I tested the fix on the public JetBrains YouTrack: https://youtrack.jetbrains.com/issues

How to Test

1. Navigate to a single issue page in YouTrack.
2. Verify that the Toggl Button appears and functions correctly.
3. Ensure that the issue ID and description are correctly captured and displayed.
