Create Submissions Tab and Modal

[FlacoJones]

• On the top of the hackathon dedicated page, add a Submissions tab (e.g. https://openq.dev/repo/SporkDAOOfficial/ETHDenver-2023)

• Create a Submissions modal with the following options

• Add Title

• Add Team Name

• Add Description (can be made into markdown/rich text later, or just text for now)

• Link to repository

• Add Bounties your applying for

This requires schema.prisma updates to add the appropriate fields to the Submission model

• Add a createdAt field for the Submission

Forms for: Name, Tagline, The problem it solves, Challenges I ran into, Technologies I used, Links, Video Demo Link, Cover Image, Logo
