Using Micromamba as the package manager

Hi. I have recently installed micromamba as my package manager and then installed in an environment called rmg_env `pyjulia` and `julia`.

However, whenever I do

```python
python -c "import julia;Julia.insta()
```

It returns an error that CONDA_JL_CONDA_EXE is empty (or rather the variable is empty so it cannot find conda). I have attempted to
```
export CONDA_JL_CONDA_EXE=/home/Calvin/bin/micromamba
```

Which then fixes that issue but the PyCall runs into the issue of doing `micromamba install numpy`. It says it cannot find the configuration file that is specified called `condarc-jl.yml`
