Add the functionality for moderators to write notes while updating user submissions

[NabbeunNabi]

Problem

As our moderation team grows we would like them to be able to leave notes for other moderators and themselves while a submission is still going through the process of being approved or rejected. This functionality is on the backend, but we have no input and are not sending any data for notes.

Success

An input is made with a test written to find it and type into it. And the data when added in the v-model field associated with it changes is sent to the backend as part of the API call.

Requirements

• Add input for a user (moderatore) to write notes in on the ModEditSubmissionForm.vue
• API call is updated to refactored to send notes when new ones are written and a submission is updated
• Once updated the input is cleared
• notes value is undefined is the input is empty
• Tests are written for the existence of the input and the ability for the user to click and type into the input

Implementation notes

• This is a link to the TypeScript UpdateSubmissionInput
• The input type is most likely a textbox
