Unable to install Vim

**Is your feature request related to a problem? Please describe.**
Vim is a go-to IDE option for quickly parsing through files & making edits. However, the default sagemaker environment does not include it.

**Describe the solution you'd like**
An option to use `sudo` (right now gives permission denied error) or vim / neovim pre-installed in the default environment

**Describe alternatives you've considered**
Working with .py and other text files using the Jupyter notebook interface
