  -extendTheme: allow passing a base theme to customize
  +extendTheme: added an optional second argument `baseTheme` to customize:
  +
  +```jsx
  +const theme = extendTheme({
  + // theme overrides
  + colors: { red: { 500: "#ff0000" } },
  + // the base theme to customize with the above overrides
  + yourTheme,
  +})
  +```
  +
  +If no `baseTheme` is provided, defaults to the Chakra theme.
