ci: globally installs codecov as part of CI pipeline

[thawkin3]

I've updated our usage of codecov to no longer be a devDependency and instead be installed globally as part of the GitHub Actions workflow in the CI pipeline.

This follows the same pattern found in the tabbable repo here: focus-trap/tabbable#261
