Chapter 3.1. Variables and Mutability. Revised Sentence

[YS-McGee]

• I have searched open and closed issues and pull requests for duplicates, using these search terms:
  • until either it itself is shadowed
• I have checked the latest main branch to see if this has already been fixed, in this file:
  • src/ch03-01-variables-and-mutability.md

Description of the problem:
The English problem is a bit of redundancy and a lack of parallel structure, which can affect clarity.

Suggested fix (Corrected Sentence):
"In effect, the second variable overshadows the first, meaning any uses of the variable name will refer to the second variable until it is either shadowed again or the scope ends."

Current Sentence:
"In effect, the second variable overshadows the first, taking any uses of the variable name to itself until either it itself is shadowed or the scope ends."
