As a developer, I want to update the form's buttons and options according to new design

#### Proposed solution

As a second step in transforming the form, form's buttons for `save` and `mark as ready` + options for `delete` and `upload XML` need to be updated following the new design. 

#### DoD (Definition of Done)

Form's buttons and options are made according to the design.

#### Testing

Peer review.
Unit tests, e2e tests
