Update linting packages to use latest

- 99% of changes were small syntax changes that were changed by the
lint command. There were a couple of small manual changes to meet the
property order patterns established as part of the vue:recommended
guidelines.

There are rules that were set from errors to warnings and new stories
are being opened to address those issues.

Testing:
- Successfully ran npm run serve
- Successfully ran npm run lint
- Verified functionality works as expected, e.g. success and failure use cases
- Resolved any JavaScript errors thrown to the console
