Weekly benchmark report - 2023

This issue gathers the results of the weekly [scheduled benchmark tests](https://github.com/jupyterlab/benchmarks/blob/master/.github/workflows/benchmark.yml).

Those test are run against JupyterLab [master](https://github.com/jupyterlab/jupyterlab) comparing the HEAD to the commit one week older than the HEAD; so every benchmark test is the evolution compared to the previous test.

For more information please refer to the [documentation](https://jupyterlab-benchmarks.readthedocs.io/en/latest/benchmarks/index.html).

Older reports are in: https://github.com/jupyterlab/benchmarks/issues/85

Start with .github/workflows/benchmark.yml to understand how the scheduled benchmark tests generate reports, then review the linked benchmark documentation and older report in issue 85. This issue records weekly results but does not define a requested change or a clear completion condition.
