chore(dependabot): skip tooling dependency updates

- Adds an ignore rule for a Microsoft Visual Studio tooling dependency in the dependabot configuration to reduce noisy PRs from non-critical updates.
- Keeps dependabot updates focused on meaningful runtime/application dependencies.
- Helps maintain a cleaner and more relevant dependency update workflow.
