Missing `liux-aarch64` builds for PyImageJ on `conda-forge`

[elevans]

There are available builds for scyjava and imglyb on conda-forge but not pyimagej:

$ mamba search scyjava --platform linux-aarch64
Loading channels: done
# Name                       Version           Build  Channel             
... (versions 0.4.0 to 1.9.1)            
scyjava                       1.10.0    pyhd8ed1ab_1  conda-forge


$ mamba search imglyb --platform linux-aarch64
Loading channels: done
# Name                       Version           Build  Channel             
... (versions 0.4.0 to 2.0.1)
imglyb                         2.1.0    pyha21a80b_0  conda-forge  

But not pyimagej:

$ mamba search pyimagej --platform linux-aarch64
Loading channels: done
No match found for: pyimagej. Search: *pyimagej*
The following packages are not available from current channels:

  - pyimagej

Current channels:

  - https://conda.anaconda.org/conda-forge/linux-aarch64
  - https://conda.anaconda.org/conda-forge/noarch
... (more help stuff)

The issue is likely due to an unnecessary restriction in our pyimagej conda-forge feedstock recipe. This issue lives here however for visibility reasons so that we can address this soon.
