Resource Estimator: Generate Docs Prototype for Scaling Overview for Services

Created by: caugustus-sourcegraph

Use the data from https://github.com/sourcegraph/sourcegraph/issues/30765 to update the guidance currently provided by the resource estimator into a static document. Add any missing services and, if feasible, disk space estimates.

In Scope:

• #37707 (closed)
• Gather feedback from CE & Design on the format
• Submit for tech review - so that all engaged teams are providing sign off that the info is correct
• #38853 (closed)

Out of scope:

• updating the resource estimator calculator (will revisit after this quarter)
