Issue: Documentation link incorrect

[elroychua]

Description:
There is an incorrect link in this project. The documentation link for React Hook Form is currently set to https://react-hook-form.com/, which does not lead to the actual documentation page. This may lead to confusion for users trying to access the React Hook Form documentation.

Possible Fix:
The correct URL for the documentation is https://www.react-hook-form.com/. Updating the documentation this correct link will ensure users can easily find and access the correct documentation.

Added notes:
On google search, it also shows https://react-hook-form.com/:

On https://www.react-hook-form.com/, expected page is shown to client:

Since this website is being powered and hosted by Vercel, the fix of this would be the site admin going to https://vercel.com/<USERNAME>/<PROJECT_NAME>/settings/domains and configrating the domain https://react-hook-form.com/ to redirects to https://www.react-hook-form.com/.
