PyCall is not using the packages in Conda

Hi,

I'm new to Julia and PyCall. I'm trying to import the Python transformers package but I'm not having any success and it appears to be a problem with PyCall not using the correct packages. I'm using Julia 1.8.5.

I don't understand why when I `pyimport("transformers")` I get an error about jaxlib being the wrong version. I confirmed that v0.4.4 is actually installed by Conda.

Here are the steps I tried.

```
julia> import Pkg

julia> ENV["PYTHON"] = ""
""

julia> Pkg.build("Conda")
Building Conda → `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/e32a90da027ca45d84678b826fffd3110bb3fc90/build.log`

julia> Pkg.build("PyCall")
Building Conda ─→ `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/e32a90da027ca45d84678b826fffd3110bb3fc90/build.log`

julia> exit()
```

```
