[OV JS] Bump NPM package verstion up to 2026.1 (#34583)
### Details:
- Update the NPM package to version 2026.1.
- Update the dev dependency 'mocha' to the beta release to fix
vulnerabilities. It will be updated as soon as a stable version is
released. (CVS-182487).
- Update the pose estimation sample to remove the use of unsupported
tfjs-node.
- The `tar-fs@3.1.2` change its behavior, causing an npm installation
failure during symlink validation. We turned off this option. This fix
works well with both versions, 3.1.1 and 3.1.2.
### Tickets:
- CVS-182504
### AI Assistance:
- AI assistance used: **yes**
- The AI Assistant helped to implement a new `getCoords` function that
uses an `ov.Tensor` rather than a TensorFlow Tensor for pose estimation
sample. This was tested by running the notebook and comparing the
results manually with those of the previous version.
