[Entry] Variables: Creating new concept entry `variables.md`

[dakshdeepHERE]

Reason/inspiration (optional)

We would like a new term entry on the variables term for dart. The entry should go under the following path docs/content/dart/concepts/variables/variables.md.

The entry should describe the term and how it is used within Dart. Also include:

• Add a "Syntax" section.
• An "Example" section that explains variables in Dart.
