Merge pull request #314629 from jlian/fix/update-page-specific-tag-example Fix specific tag examples in IoT Edge update page

Fix specific tag examples in update page to use three-part versions The 'Update a specific tag image' section defines specific tags as using all three version values (e.g., 1.5.0), but the examples showed 1.5, which is a rolling tag. Updated examples to use 1.5.1 to match the section's own definition and avoid confusing rolling vs specific tags.
