[FDS-2466] Update references to schema location in config.yml

[jaymedina]

problem

A user reported lack of clarity in the expected location of the model schema in the Confluence documentation (see ticket for more context)

solution

The README documentation in the schematic repository is now the single source of truth, so I went ahead and moved sections around to improve the flow of the doc.

Changes:

• Moved the Set up configuration files section below Google credentials section. Now, schematic users will set up their Google credentials and download their relevant schema file before setting up the config.yaml, at which point the instructions in section 6 are clear for where the schema file should live.
• Changed config.yaml update example so that users can see how they would modify the path to their model schema in the config.yaml.
• Moved the IMPORTANT banner in section 4. Get your data model as a JSON-LD schema file to section 6 because it flowed better with the new example from above.

I've cancelled the test (3.10) check since these changes only affect the README.
