fix: dependabot configurations

[mohnoor94]

Situation

Dependabot was unable to detect and update our configured dependency files effectively.

The property '#/updates/1/ignore/0' contains additional properties ["directories"] outside of the schema when none are allowed
The property '#/updates/1/ignore/0/update-types/0' value "all" did not match one of the following values: version-update:semver-major, version-update:semver-minor, version-update:semver-patch

Task

• Fix the issue by configuring maven updates to be applied to the examples folder only.

Action

• Fixed invalid properties in .github/dependabot.yml
• Updated Maven config to target examples/** only

Testing

Post-merge, verify that Dependabot updates:

• Maven dependencies in the expected folders (excluding code).
• GitHub Actions dependencies in .github/workflows.

Results

• Dependabot configuration passes validation
• Maven updates correctly scoped to examples
