Software deployment diagram legend is illegible

[pburkholder]

In order to communicate with JAB and other parties we want legends to be legible.

Comment from JAB TRRs:

Legend is not detailed > data flow arrows should show input, output, and two-way flows as applicable.

Security considerations

None. This will require reformatting/redrawing already public information.

Implementation sketch

Pursue one of:

• Restore lost styling information
• Look at embedding directly in GitHub per https://github.blog/2022-02-14-include-diagrams-markdown-files-mermaid/
• Embed in cg-site as we do for, e.g., https://cloud.gov/docs/management/custom-domains/
