Update names, titles and tags for examples with real data (#2416)

### What
Updates the titles, and adds tags to all "python examples with real
data" (a separate PR is needed for the "fake data" examples).

Renames:

| before | after |
| --- | --- |
| arkitscenes | arkit_scenes |
| colmap | structure_from_motion |
| deep_sdf | signed_distance_fields |
| dicom | dicom_mri |
| mp_pose | human_pose_tracking |
| nyud | rgbd |
| opencv_canny | live_camera_edge_detection |
| ros | ros_node |
| segment_anything | segment_anything_model |
| stable_diffusion | depth_guided_stable_diffusion |
| tracking_hf_opencv | detect_and_track_objects |

In order to minimise merge issues, this is best updated and merged

TODO

- [x] Update names script names
- [x] Update any references to the scripts
- [ ] ~~Mirror updates for Rust examples~~ (none of the renamed examples
have rust counterparts)
- [x] Convert tags to list
- [x] Quick typo/grammar pass with pycharm's checker
