As a volunteer I want to be able to update my profile information

Available to all users to view and update their profile information

**Tasks**

Frontend
- [ ] Profile page
- Change the profile page that the template currently has
- Display all of the logged-in user's details
- Add an edit button (maybe top right of the page?)
- When the edit button is clicked, turns the information fields into input fields and add a save or cancel button to the page (maybe bottom of the page?)
- Clicking save will use a backend API endpoint to update the profile (see below) and clicking cancel will turn edit mode off with no information change

Backend
- [ ] Retrieve profile endpoint
- GET request, given a user id, return all of the information about this user
- Create a new role (e.g. `read:user`). if the person making the request has this role, allow access to any profile. Otherwise, only allow them to see their own profile
- [ ] Edit profile endpoint
- PATCH request, given a user id and a user profile in the request's body, update the user profiles so that it matches the request
- Create a new role (e.g. `update:user`). if the person making the request has this role, allow access to any profile. Otherwise, only allow them to update their own profile
