BUG: Latest PyTensor versions not available in conda?

Describe the issue:

When I execute conda search pytensor

I received

but unfortunately I need >=2.28.2 and <2.29. With pip I can see later versions but the developers for pymc-marketing encouraged me to install pytensor with conda. Any suggestions?

Reproducable code example:

conda search pytensor

Error message:

PyTensor version information:

trying to install 2.28.2 or later

Context for the issue:

No response

Start by reproducing conda search pytensor and compare its results with the requested PyTensor range (>=2.28.2 and <2.29). The issue does not mention repository files, tests, or a packaging entry point; done would mean determining why those versions are absent from the conda results and documenting or resolving their availability.
