Error when load plugin from aiidalab/full-stack image

See the comment from https://github.com/aiidalab/aiidalab-qe/pull/1282

To reproduce the error
```
docker run -it ghcr.io/aiidalab/full-stack:2025.1026 /bin/bash
```
then install `aiidalab-qe`, then run this:
```python
>>> from aiidalab_qe.plugins.pdos import pdos
Failed to load plugin entry point pdos.
This may be due to compatibility issues with the current QEApp version.
Please contact the plugin author for further assistance.
Thus, the plugin will not be available. However, you can still use the rest of the app.
Error message: partially initialized module 'aiidalab_qe.plugins.pdos' has no attribute 'pdos' (most likely due to a circular import)
