Bash completion support for the mamba command

This extends the conda-bash-completion project to work with mamba by adding support for the repoquery command and its options.

The easiest way to install this feature is via the mamba-bash-completion package:

mamba install -c conda-forge mamba-bash-completion

This is really just a thin wrapper to tweak conda-bash-completion so see that project for details.

NOTES

minimamba

The minimamba executable is built on cli11 and has its own completion support built-in, so we are not going to mess with that 😉.

Thanks

Thanks to @sixvable for introducing me to mamba by suggesting this project. 😄
