web -> locations -> /wp/wp-content/uploads doesn't have expires

[cborup]

In .platform.app.yaml
web:
locations:
"/wp/wp-content/uploads"

Doesn't have expires, making it default to -1.
In a setting with varnish (in our case Fastly) in front of WordPress this leads to much needless trafic to the backend server

@cborup we haven't historically added caching to the uploads directory, leaving that to the end user/developer to add if/when they choose to implement caching. HOWEVER, I think we should, and then add a note that it's enabled in our docs.

Please see the most recent PR here, and let us know if this will address your concern/request.

Thanks @gilzow this would indeed have solved our problem.
