Background

There will be times when a user needs to manually add in an issue or pull request into their week in review, that is not showing up already.

Now that there is a BE mutation for this, we need to wire up the FE.

Definition of Done

• When user pastes URL into FE form, it sends mutation to BE to smartly add it to their WeekInReview
• create FE mutation request
• leverage loading from mutation to display something in the UI during processing
• refetchQueries to update the page with the new Statistic in the appropriate categories
• SweetAlert showing success/failure
