[Term Entry] C++ Variables Mutable Variables

[codecademy-docs]

Reason/inspiration (optional)

We would like a new entry on the Mutable Variables term under C++. The entry should go in a new file under docs/content/cpp/concepts/variables/terms/mutable-variables/mutable-variables.md.

The entry should include:

• An introduction to the concept
• A Syntax section that provides the syntax for the concept
• An Example section that provides an example demonstrating the concept in use
• A Codebyte Example section that provides a codebyte example demonstrating the concept in use

Please refer to the term entry template, content standards and markdown style guide when working on the PR for this issue.
