CI broken

Description

Since a day or so, the CI is broken.

The pathologic error seen are:
For JS tests when running jlpm run build

error TS2688: Cannot find type definition file for 'node'.
  The file is in the program because:
    Entry point of type library 'node' specified in compilerOptions
Error: ../observables/src/observablemap.ts(4,29): error TS2307: Cannot find module '@lumino/disposable' or its corresponding type declarations.

For other tests

$ node scripts/ensure-buildutils.js && node buildutils/lib/ensure-repo.js --force
internal/modules/cjs/loader.js:905
  throw err;
  ^

Error: Cannot find module 'fs-extra'
Require stack:
- /home/runner/work/jupyterlab/jupyterlab/scripts/ensure-buildutils.js

sh: 1: prettier: not found

etc

See for example https://github.com/jupyterlab/jupyterlab/pull/12899/checks

By curiosity I ran a second time the JS tests on the last master commit that passed and it failed (you can see it by switching from attempt 1 and attempt 2): https://github.com/jupyterlab/jupyterlab/actions/runs/3035624109

This calls for an external impact - certainly related to the pip install -e .[dev,test] that does not run jlpm install on the current folder.

In the rerun of the last working commit, the Installation dependencies took 1m40s in the failing case and 5m56s in the working one. Also in the working case there are multiple line Building editable for jupyterlab (pyproject.toml): still running... when there is only one in the failing case.

A candidate is the latest release of https://github.com/jupyterlab/hatch-jupyter-builder

Another candidate is hatchling v1.9.0: https://github.com/pypa/hatch/releases/tag/hatchling-v1.9.0

Some discrepancy seen with hatch-jupyter-builder.

With version 0.5.3, pip install -e triggers: hatch_jupyter_builder.utils:With kwargs: {'build_cmd': 'build', 'source_dir': 'packages', 'build_dir': 'dev_mode/static', 'npm': ['node', 'jupyterlab/staging/yarn.js']}
With version 0.6.1 (0.6.0 was not published apparently), it triggers: hatch_jupyter_builder.utils:With kwargs: {'build_cmd': 'build:prod:minimize', 'path': 'jupyterlab/staging', 'source_dir': 'jupyterlab/staging', 'build_dir': 'jupyterlab/static', 'npm': ['node', 'yarn.js']}
