[CT-1515] [Docs] pre-commit install

[dbeatty10]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

Add installation of pre-commit hooks to the contributing instructions. Namely,

pre-commit install

Also

We'll probably want to add the same instructions to all the dbt adapters + the adapter project generator/scaffolding template.
