@lresende are we handling the additional stuff from #2711 in a separate PR, such as updating docs and deprecating/removing the code-viewer-extension package?

[lresende]

I want someone other than me to confirm it has been switched properly, and I can handle the other clean-up items with additional commits.

[caponetto]

NP! I can build and test it locally too.
As I'm unfamiliar with all the use cases for the Code Viewer extension, could you please provide the steps for this test?

[shalberd]

We should also

• remove the reference to elyra-code-viewer package https://github.com/elyra-ai/elyra/blob/main/pyproject.toml#L179
• and do the rest of the suggested items Switch to using the Code Viewer in core Jupyterlab #2711 (comment) in this PR, too.

Edit:

I want someone other than me to confirm it has been switched properly, and I can handle the other clean-up items with additional commits

Ah, I see, good idea.

@lresende nice work, looks good to me, too. Neat to see this kind of functionality "ability to display a given chunk of code (string) in a transient read-only ‘editor’ without needing to create a file" in Jupyterlab now.
