Create Workshop Frontend workshop service and create workshop page - Frontend

[Littlesk]

What?

• Update the create workshop frontend to type check and validate all the form values. Include errors when appropriate. Then pass it to the workshop service. The user is pulled from the site and added to the workshop as the host.
• Create a workshop service for the forum that will call the backend and submit the workshop to the backend.

Why?
We want users to be able to create workshops. We also want to make sure that the values the user inputs in the workshops are valid. We don't want the user to have to input themselves as the host.

Acceptance Criteria:

• When a user inputs an invalid value into the form it is caught and an error message shows up. This is for all values.
• When a user hits submit and everything is correct it gives a success message.
• User is added to the workshop as the host without them needing to add themselves.
• When everything in the workshop is valid it correctly transfers the workshop to the backend.
