Resolve firmware accessibility violation

The Bootstrap-vue b-form-group component has two different HTML blocks
that are generated depending on what props are present on the
component. Neiter of these are correct for wrapping a button since
it is not semantically correct to wrap one button alone in a fieldset
or to associate a <label> element with a button.

- Remove the b-form-group comonent that contains the submit button
