refactor: Simplify validation handling in GitHubIssuesView

- Removed the isValidating prop from GitHubIssuesView and ValidationDialog components to streamline validation logic.
- Updated handleValidateIssue function to eliminate unnecessary dialog options, focusing on background validation notifications.
- Enhanced user feedback by notifying users when validation starts, improving overall experience during issue analysis.
