Robotics: update cross-references in Reference to MyST standards

The mentor for this issue is @geofreynyaga

Background

Reference pages use relative Markdown links to other documentation pages. For example, in docs/references/workshop/ros2-minimal-sdk.md, ROS 2 development using Workshop links to ../../tutorials/workshop/ros2-dev-workshop.md. Replace these with MyST references so links are resilient to file moves and use meaningful page or section anchors.

Scope is limited to docs/references/ and its subdirectories.

Task

1. Review documentation-page links in docs/references/ that use relative paths. Do not convert image or other asset paths.
2. Replace each relative documentation link with a MyST reference. Use a page's level-1 heading when the link is to the whole page; otherwise, reference the relevant section heading.
3. Add labels where required. For level-1 headings, use the folder-subfolder-title-slug convention, with concise, unique lowercase slugs; for the linked Workshop page in the example above, use (tutorials-workshop-getting-started)=.
4. Check every new or changed label manually: it must be meaningful, unique, and follow the convention.
5. Run make clean, then make run. In the local site, manually click every changed link and confirm it reaches the intended page or section.
6. Run make linkcheck; it must pass.
7. Open a pull request against the repository and sign the Canonical contributor license agreement.

Outcome

Documentation-page links in Reference use MyST references, their anchors follow a consistent convention, and all changed links have been manually verified.
