[Task] Exclude Non-Code Assets From Certain Build

[ianjensenisme]

Description

Currently the full set of GH workflows runs on every commit to Main, but this is probably overkill when, for example, we update a Markdown.

We need to add workflow exclusions when certain file types (or possibly certain file types in certain locations) are updated.

Definition of Done

- A markdown update in this repo does not trigger a deployment test.
- Code updates in this repo still trigger deployment tests.
- Markdowns are still linted and otherwise scanned appropriately.
