first pass at updating Billing Project guidance

[KatherineCox]

Thought this would be fairly straightforward, just recommend they use a single Billing Project to start. But two snags:

• It now makes more sense to swap sections 5 and 6, since Google Projects won't exist on GCP until Workspaces have been created, so there won't be anything to track spending for until they create Workspaces.
• This means we need to update the overview figure.

So, here's a start at updating the prose, but I need to address those two issues before this is ready to go Done!

Those might be better addressed in a separate PR? Nah, that'll just make merging harder.

Before I started working on Billing videos, my original goal was just to update the Getting Started text to reflect the change to 1 Workspace: 1 Project.

Then I realized I needed to update the overview figure, which seemed like a good opportunity to also make a Billing short...which keeps growing into more videos, haha.

So, in the interest of making some incremental forward progress, here's PR that just updates the prose and overview figure but does not include any of the new videos. I'll add videos in other PR(s), once they're ready.

Major changes

• now recommend they only set up one Terra Billing Project to start (keep it simple)
• swap order of steps 5 and 6 (Set Alerts/View spend <-> Create Workspaces)
• updated overview figure to reflect the reordering
• (also updated the _child_google_billing_view_spend in Update _child_google_billing_view_spend.Rmd AnVIL_Template#118)

So, primarily take a look at PI steps 4, 5, and 6 (i.e. chapters 2.5-2.7)
