Implement create_initial_prompt for website

[othrayte]

There is a way to rank initial prompts but we seem to be missing a page to create initial prompts, which I think is a thing we can do in the discord bot.

Do we have the backend for this?

At least in the protocol, we have a task type called rank_initial_prompts or something

[othrayte]

We also already have the website front end for ranking the initial prompts (which functions and I assume records the results in the backend) just seemingly no way to create them, that is what originally prompted me to create this issue.

Thank you for pointing this out.

In the backend, I believe the task type is called initial_prompt. It doesn't really return anything other than a task id. I'll assign it to @othrayte :)
