This function automatically searches for available conda executables in common system paths.
If none are found, it offers to install Miniconda using the reticulate package.
Value
A character string with the full path to the selected conda executable, or NULL if no conda was found and the user declined the Miniconda installation.
Details
The function first checks if conda is available in the system PATH. If not, it searches for common installation
directories of Anaconda and Miniconda. If still no installation is found, the user is prompted to install Miniconda.
Once a valid conda executable is found (or installed), its directory is added to the current R session PATH.
