Fix build for latest yarn/jlpm

Move to jlpm to make sure we are in sync with JupyterLab quirks.

Currently, jlpm is on yarn 3. To make the package work with that I had
to:
* Run `jlpm install` to change to the new lock file format.
>  ➤ YN0028: │ The lockfile would have been modified by this install, which is explicitly forbidden.
* Change the CICD step that ran Jupyter in detached mode as yarn doesn't
  seem to respect the `&` operator at the end of command targets any
  more and won't run the target in the background.
* Use PnP loose mode of yarn. This one applies due to transative
  dependencies not complying with recent yarn rules.

NB that I pinned the version of JupyterLab to below 4.
