Typo Chapter 12 Networked Programs

[nicolopz]

There are two typos in the HTML book https://www.py4e.com/html3/12-network
They are located in the title and the third sentence.

1. HyperText Transfer Protocol - HTTP
   The first "t" should be lowercase:
   Hypertext Transfer Protocol - HTTP
   https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol

2. In the sentence, "The network protocol that powers the web is actually quite simple and there is built-in support in Python called sockets..." sockets should be socket.
   This is how it is mentioned in the reference.
