Chakra 2 Fixes

[csandman]

• Replace all type casting in multi-value.tsx with custom type guards.
  • Would like to remove the type casting on CSSObject but that appears to be a bug with Chakra UI itself.
    • The CSSObject type is missing custom pseudo selectors included in the theme chakra-ui/chakra-ui#6263
    • Typescript: Property '_hover' does not exist on type 'CSSObject'. chakra-ui/chakra-ui#6261
• Replace the deprecated StylesProvider component and useStyles hook with the createStylesContext function.
  • This change involved merging the components that utilized the same styles object into the same file.
  • This is not documented on the website but it is clear if you look at the code.
• Remove all instances of the ReactElement type from custom components as it wasn't offering any benefit.
• Remove the data-focused prop from the ClearIndicator component as it had no purpose.
• Unify the definitions for all icon components to remove the React.FC typings and always use the @chakra-ui/icon component.
• Add zod React Hook form examples to the README
• Add missing innerProps to components that should have them - closes [BUG] Can't add custom props for MenuList via innerProps #152
