MN Sediment - Add citation and warnings to report

[amedenblik]

Parent issue is #1544

In the "Sediment Model" section of the report:

• At the top of the sediment model report section, add a yellow warning box that contains warning messages or disclaimers about the sediment model. We will need to coordinate with Will Lund and Joel Groten about what these might be.
• At the bottom of the sediment model report section, add a Citations section that includes these citations. The text should link to the reports. We should double-check that these citations are formatted correctly for USGS citations (I don't think they are).
