chore(core): correct grammar to make README more easily readable (#724)

Hey, I really appreciate the work put into this integration. I have gone
through the README and corrected some grammar (although most was great)
to make it easier to read/clarify what I think you were trying to say in
fewer words!

Keep up the work!

 ### Tapo protocol
 
-Tapo is updating its devices with a new firmware which use a new protocol called KLAP. This integration support it's but if you running older version your devices maybe cannot works. So please keep this integration up to date by using HACS!

 ### Local Integration
 
-Although the integration works using LAN, the tapo device needs internet access to synchronize with tapo cloud, especially for credentials, a missing internet access could lead into "Invalida authentication error". Also a static IP must be set for device.

 ### Authentication
 
-For some unknown reason email with capital letter thrown an "Invalid authentication" error. So before open an new issue check your email address on Tapo App Settings. If contains capital letter, the integration won't work. I've opened an issue that explain this [#122](https://github.com/petretiandrea/home-assistant-tapo-p100/issues/122), I will fix asap. As workaround you can create a new account using all lower-case in your email address.
