feat: Initial implementation of copa extension

[jgrer]

• Added a switch to tell the extension if the user is using containerd image store or not
• Inserted a tooltip next to the switch that links to the docker documentation explaining containerd image store
• Added MUI icons package to use the information icon for the tooltip
• fetchData() is now called when the user selects containerd image store instead of when the app component first renders
• Added client-side validation to make sure an image name is supplied with a tag
• Created a new component, commandline.tsx, that displays a formatted version of the stdout and stderr from the copa-extension container
• Added an IconButton using the ChevronRightIcon and ExpandMoreIcon from the MUI icons package to show/hide the command line component whenever needed
• Removed View Copa Output button and Dialog because of the new dropdown command line feature
• Fixed style error with the label for the scanner input being covered by the border of the select component
• Fixed style error with the Copa Version and Trivy Version select boxes being misaligned
• Fixed the svg file for the Copa logo having a white background

@jgrer the PR needs a semantic title, for example "feat: Initial implementation of copa extension". Also PRs with commits under project-copacetic need sign-off. You can amend your commits with the git commit --amend -s command to include signoff via -s.

when running this locally with nginx:1.21.6, I see "Failed to patch nginx:1.21.6: Undefined error." and the following on the console: docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "nginx:1.21.6": executable file not found in $PATH: unknown. Maybe I am missing something from the setup?

For errors that don't match one of the cases, we should also add a default message to prevent undefined.
