Add text to Step 1 Project description to clarify it won't be exported to Word

[DerekMolnar]

Changes
Add text above the manual input section Project description stating:
"Note that the text you provide in this section is stored in DAMAP as part of the RDA Common Standard for DMPs [https://github.com/RDA-DMP-Common/RDA-DMP-Common-Standard?tab=readme-ov-file]. It will not be visible in the exported Word DMP"

Additional notes
workaround related to #325

Assumptions
It is assumed that if this text was added as a Tooltip or Info box far fewer users would read the text, hence the decision to add as text above the section.

Acceptance Criteria
Text should be visible and link should be embedded in the text RDA Common Standard for DMPs

Are there maybe other fields that do not get exported?
Someone should check, so we can do all of them together.

I've gone through my notes and have created issues for all items I identified as not exporting. I have closed master issue https://github.com/orgs/tuwien-csd/projects/1/views/21?pane=issue&itemId=68134299&issue=tuwien-csd%7Cdamap-backend%7C204
