Description
Running the [Google Colab](https://github.com/imagej/pyimagej/blob/main/doc/Install.md#dynamic-installation-within-google-colab), example, I get the following exception running this line:
```python
ij.py.run_plugin("Filter Rank", {"window": 3, "randomise": True}, imp=imp)
```
```
[java.lang.Enum.toString] java.lang.VerifyError: (class: Filter_Rank, method: setup signature: (Ljava/lang/String;Lij/ImagePlus;)I) Incompatible object argument for function call

Can anyone else replicate this?

Research direction
Start with doc/Install.md's “Dynamic installation within Google Colab” example and reproduce the ij.py.run_plugin(...) call in Colab. Compare the environment and installed components involved in the VerifyError; done means the documented example runs without the exception or the documentation records a verified incompatibility and corrected instructions.
