fix issue pressing enter to submit form

fixes CNVS-21292

Button type wasn't set on a form button which was causing issues

Test Plan
Given I'm a user that can create modules(chrome, safari, firefox)
And I'm on the modules page
When I click "Add Module"
And fill in a module name
And press enter
Then the form should submit
And the dialog should close
And the new module should appear on the page
