[Concept Entry] Sklearn linear-models

[codecademy-docs]

Reason/inspiration (optional)

We would like a new entry on the Linear Models concept under Sklearn. The entry should go in a new file under docs/content/sklearn/concepts/linear-models/linear-models.md.

The entry should include:

• An introduction to the concept
• A ‘Syntax’ section that provides the syntax for the concept (if applicable)
• 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 concept entry template, content standards, and markdown style guide when working on the PR for this issue.
