Navigation using VIM "gg" and "G" in Container Config tab

**Is your feature request related to a problem? Please describe.**
Cannot easily navigate to end of file or go to end in `Container Config` tab present in the container panel. The container config can be pretty long.

**Describe the solution you'd like**
1. **Vim keybindings** for navigation here
- `Shift + g` -> go to end/end of file
- `gg` -> go to top/start of file

**Describe alternatives you've considered**
None

**Additional context**
Can add this and raise a PR for same if approved.
