[BUG] .wash folder not created, context commands error out

[ghost]

Describe the bug
A clear and concise description of what the bug is.

The .wash folder was not created on my computer, and when I try to use the wash ctx commands they fail on a missing directory.

To Reproduce
Steps to reproduce the behavior:

1. Install wash from cargo
2. Attempt to follow wasmCloud Getting Started guide, using Docker Compose
3. Try to create a context using wash ctx.
4. Error Error: No such file or directory (os error 2)

Expected behavior
The .wash folder should be created, either when the tool is installed, or all commands that use it should have the ability to create the folder on the fly.

Screenshots
If applicable, add screenshots to help explain your problem.

**Environment (please complete the following information) **

• OS: macOS Big Sur 11.6.1
• Shell: zsh
• wash Version: 0.7.2

I'll see if I can fix this myself. It should be fairly simple to make the commands create the .wash folder if it is missing.
