Frontend code submission for FLIP fest 'Playground Feature: Markdown READMEs 18'

[hichana]

Closes: N/A

Description

This PR comprises the work by @J00LZ and @hichana on the FLIP fest 'Playground Feature: Markdown READMEs 18'. It adds a 'PROJECT' section that allows the user to create a title, description and readme for the project, with functionality integrated into the export feature (ex. the readme.md file exports with the rest of the code) and various redirects schemes to enhance the user experience.

We made a comprehensive guide with screenshots to illustrate the features: https://github.com/hichana/flip-fest/blob/submissions/issue-%2318/milestone-%232/TeamExponential/submission/issue-18/milestone-2/TeamExponential/README.md

Thanks for the feedback @MaxStalker. I've made all the changes, and also added an eof space to Spinner.tsx, which also lacked one. Please let me know if anything else comes up with this submission.
