Summary
Updates the React-USWDS Typescript version to 4.0 (actually 4.2.4, which is the most recent TS version, and also what USWDS is using in their latest release). This required updating the
@typescript-eslint
plugin and parser, which required changing some linter exception comments in a story file to solve an eslint error that arose with the plugin version change.The updated plugin also threw quite a few warnings around wanting
argTypes
parameters in story files to be typed, so I went ahead and added those, and fixed a few other minor type-checking complaints that existed elsewhere to get back to a warning-free baseline.As we're updating a dependency major version, this is a BREAKING CHANGE.
