need to update syntax highlighter I think ... @rogermparent @yathomasi could you pls help / guide where and how it can be done pls?

[rogermparent]

We've been working on the syntax highlighter, last I remember @yathomasi is on it right now and we're parked at a spot where we don't currently have a good way to grab/update the highlight definitions we share for dvc/cml/mlem since they're generated from the sidebar.json system and are difficult to share as a result. It's already pretty high priority, but we can bump it higher since it seems like the issue people are running into most.

[yathomasi]

For alias please update: https://github.com/iterative/dvc.org/blob/main/content/linked-terms.js
For the addition of new commands:
- we need to update respective command file here
- I did write a rough script to update the commands a while back expecting this same situation. Now, we can bump up to higher priority and I think we can update this into GHA to create PR with CML.

The one @rogermparent mentioned is for cross-websites command line linker. draft PR

dvc list-url has been merged. Could someone do a final review please?

@yathomasi Should I send a PR simply adding list-url to gatsby-theme-iterative?

[rogermparent]

Thomas is on vacation, so I'll help you see this through. We're just adding ls-url and list-url to dvc, right? I opened up this PR for that. Sorry for not helping out for so long, I actually just glanced by a few times and assumed the issue was handled with the information.

[dberenbaum]

LGTM. @rogermparent I approved iterative/gatsby-theme-iterative#89. Do you want to merge that first and then this one can be merged?

[yathomasi]

The theme is updated and merged into this PR as well. The changes should be reflected on the preview deployment.

[rogermparent]

From the preview 🎉
