PR Summary

• Update to tailwindcss Configuration Path
  The cssPath in the tailwindcss configuration has been updated. It now includes an additional option injectPosition, which allows for more flexibility in the positioning of css.

• Enhanced Exposure Level Control
  The exposeConfig property has been adjusted to contain a level property. This allows for greater control over how exposed our configuration is. Note that the exposeLevel property has consequently been removed from the tailwindcss configuration.

• Removal of Redundant Properties
  The injectPosition property has been removed from tailwindcss configuration. This keeps the codebase cleaner and more efficient, avoiding unnecessary redundancy.

• Simplification of the Config Path
  We've simplified the configPath property. It's now just tailwind.config, which is much easier to understand and manage.

• Default Configuration Update
  The default config property has been updated to an empty object. This ensures that our configuration starts from a clean state, mitigating chances of unwanted behaviors.

• Enabled Viewer By Default
  By default, the viewer property is now set to `true'. This ensures that all developers can view the tailwindcss configuration without having to change any settings.
