Update link to Fabrik documentation on homepage

[nikochiko]

• Currently, the link to the Fabrik documentation in the "PROJECTS" section of the homepage points to the outdated Fabrik Wiki (see this Fabrik issue: [Wiki] Fabrik Wiki outdated, mentions IDE instead of Fabrik. Fabrik#522).
• For consistency, because the documentations of both EvalAI and Origami point to their readthedocs.io pages, it would be better to change this link to https://fabrik.readthedocs.io/en/latest/ .

Hey there! If this issue is still open to solve, I would love to solve this!

Hey @nikochiko Can I work on this?

[nikochiko]

@sohamsshah Sure! Go ahead.

Hey @nikochiko I went through the codebase and I suppose that the url that links to the fabrik project is actually in that DB, which is hosted on AWS RDB. Can you assist me upon that? Or if any better/effective alternative is available, I would be ready to implement it.

Nice catch, I think you're right. I suggest you take on some other issues for now, maybe in Cloud-CV/EvalAI.
Docs link isn't such a big deal, but I'll just ping @RishabhJain2018 to let him know.
