Refactors our help sidebar within Studio to include the actual support
form itself when contact is selected. This PR also cleans up the initial
state of the sidebar and the options within.
## To test:
- Open an org and click the help icon top right
- Click contact support
- Submit a support ticket
- Click done to return to support sidebar state
