chore: update deps incl webpack5. Add explicit children prop to work with react18 typedefs

[jafin]

Original intent of change was to update typedefs for React 18, it evolved into a few other build changes:

• Update webpack 5 + ts-loader for build
• Emit single .d.ts typedef in dist.
• Add explicit children prop to work with changes in react 18 typedefs that removed the implicit children prop.
• Make tests run under React 18.
• Dropped @stae/linters. Receiving errors about missing unicorn lib !??!? Could not determine what linter rules this was configuring (feels outdated?)
• Add prettier config to ensure single quote stye of package is linted.

Note: I couldn't run the test command locally, so the line was changed to something I could run.

Please review.
