Updates to docx template

[erika-tyagi]

Hey @wcurrangroome! Copying over the to-do list you mentioned from Slack:

• Front page header
• Front page banner image
• Table of contents
• Urban logo for figures
• Formatting of the "About the Urban Institute" section on the last page
• Images have to be manually set to "Square with Text Wrapping" or similar, and moved around by hand, after converting to .docx, which is a pain - I've got a question about this but Posit folks haven't responded yet.
• Footnotes
• Endnotes
