This pull request bumps the version to 4.16.0 for a minor release with:

• Code playgrounds as a Papyros component (Share rendering and helpers between the sandbox components #1169, Let several Papyros instances share one runtime #1168, Add a code playground component #1170, Show a code playground's data files as read-only tabs #1171, Add a demo page with code playground scenarios #1185): several Papyros instances can share one PapyrosRuntime (one worker per language, runs routed by run id), <p-code-playground> is a small runnable editor with output, input(), tracebacks and read-only data file tabs, and playground.html is a demo page. The sandbox shares its error, output and tab code with the playground: tracebacks open behind a "Show traceback" button, the boot shows as Loading while Run and Debug stay available, and Papyros.unsupported_browser reads "Python could not start in this browser. Close other tabs, update your browser or use another one."
• Stay quiet when an instance is disposed while Python boots #1239: an instance disposed while Python boots no longer reports a launch error or asks to retry.
• Translate CodeMirror's completion list label in Dutch #1236: CodeMirror's completion list label is translated in Dutch.
• Load the vite configs as ES modules and install only chromium in CI #1237, Type-lint the tests and adopt dodona's deprecation and sort rules #1238: the vite configs load as ES modules, CI installs only Chromium, and the tests are type-linted.
• Dependency bumps: Bump the eslint group with 2 updates #1230 (eslint group), Bump the codemirror group with 2 updates #1231 (codemirror group), Bump vite from 8.3.4 to 8.3.5 #1232 (vite 8.3.5), Bump playwright from 1.64.0 to 1.64.1 #1233 (playwright 1.64.1), Bump browserslist from 4.29.3 to 4.29.4 #1234 (browserslist 4.29.4), Bump typescript-eslint from 8.71.1 to 8.72.0 #1235 (typescript-eslint 8.72.0).

Minor rather than patch: PapyrosRuntime, <p-code-playground> and the files option of runner.start() are new public API; new Papyros() without options behaves as before.

After the merge, pushing the tag v4.16.0 publishes to npm and creates the GitHub release. Dodona then pins it in https://github.com/dodona-edu/dodona/pull/9304.
