[Term Entry] C++ Sets: swap()

[codecademy-docs]

Reason/inspiration (optional)

We would like a new entry on the term swap() under sets in C++. The entry should be in content/cpp/concepts/sets/terms/swap/swap.md

The entry should include the following:

• A description of the term
• A ##Syntax section that includes the syntax of the method and its details
• An ##Example section that show an example of the current entry.
• An ## Codebyte section that have a compilable code inside it showing the current entry in use. Use ```codebyte/cpp to add compilable code.

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