Feature Request: VSCode support for jupyter `sas_kernel`

[ryanzomorrodi]

This issue mirrors #336 and quarto-dev/quarto-cli#5616 but for sas_kernel support.

Like the prior issues, this one would aim to extend support in the form of

• Generating a run cell button for sas cells
• Allowing code to be executed with ctrl+enter
• Adding syntax highlighting from the official SAS extension or others like it
• Adding code completion from the official SAS extension or others like it

Thanks for all your efforts and any help you can offer!
