Update docs deployment pipeline to use --static CLI Flag

[jeancochrane]

In 1.7.1, dbt added a new --static command line flag to dbt docs generate that bundles the manifest, catalog, and index files into a single static HTML file (dbt-labs/dbt-core#8614). Using this flag should allow us to simplify our docs deployment pipeline, since currently we have to save and deploy manifest.json and catalog.json files along with index.html. If static docs work as well as the old approach, we should switch to it to make our deployment pipeline simpler and easier to maintain.

Depends on #356 landing in order to upgrade our project to use dbt 1.7.* and make this flag available.
