Add a jobs posting page form

[NiallJoeMaher]

Context

We want to be able to add job postings. The first task is creating a form for entering a job. This issue concerns creating a responsive form where users can add a job posting.

It should look something like this:

Expected Behavior

• We are using the following components (already in the codebase) and they should not need updating: https://catalyst.tailwindui.com/
• As for responsiveness, it should work like this page: https://catalyst-demo.tailwindui.com/settings
• It should have the same sized text and work as shown in that page too (https://catalyst-demo.tailwindui.com/settings)
• The labels and text values/placeholders should have the same as shown in the design (figma below)
• This page should be feature flagged with a flag called "course-video". For an example of a feature flag see https://github.com/codu-code/codu/tree/develop/app/(app)/feature-flag-example

This is a frontend-only task that requires only the frontend aspects.

Another issue can be created to handle error handling and data validation. Another issue can be created to handle wiring up to backend and stripe.
