Update write-up submission instructions

[tschaffter]

We now want the participants to share their Synapse project (write-up) with the organizers as soon as they have submitted it. We need also to provide information on the validation process of the write-up.

On this staging page: https://www.synapse.org/#!Synapse:syn18405992/wiki/595123

• [x] Add information about 1) how to share the project and 2) the validation process (Thomas)
• [x] Create write-up dashboard that shows the submission status (Tom)
• [x] Review of the page by Tom
• [x] Review of the page by Tim
• [x] Mirror to the public site (Thomas)
