chore(deps-dev): bump jupytext from 1.19.1 to 1.19.3

[dependabot]

Bumps jupytext from 1.19.1 to 1.19.3.

Release notes

Sourced from jupytext's releases.

Version 1.19.3

Fixed

• The Jupytext CLI issues a warning when a notebook is not trusted. Also, trust is preserved when empty outputs are added (follow-up on #1505)

Changed

• The dependabot config has been updated to correctly bump extension packages, now allowing only production updates and ignoring dev dependencies (#1532). Thanks to Mahendra Paipuri for this PR!
• Removed deprecated stylelint packages (stylelint-config-prettier and stylelint-prettier) from the JupyterLab extension dependencies (#1530)
• We have removed Python 3.9 testing from the CI (Python 3.9 reached EOL in October 2025)

Version 1.19.2

Fixed

• Trusted notebooks remain trusted after jupytext --sync (#1505)
• We have fixed the homepage link in package.json. Thanks to Michał Krassowski for making this PR (#1494)
• Thanks to Brigitta Sipőcz for fixing a broken link in our CLI (#1428)
• The --quiet flag now suppresses the creating missing directory warning when writing to a path that includes a prefix (#1533)

Changed

• The CI workflow has been restructured to maximize parallelization. All test suites (pip, conda, UI) and the build step now run concurrently after pre-commit checks, instead of sequentially, reducing CI times (#1527)
• We have skipped the tests that involve jupyterfs on Python 3.12+ as they started failing on the CI with no obvious way to fix them (#1509)
• We have changed the configuration of Dependabot to get grouped dependency updates for our JupyterLab extension.
• We have merged a series of Dependabot security updates: #1516, #1517, #1519, #1520, #1522, #1524
