As a Wikidata Bridge tester I want to save a first dummy edit.
**BDD**
GIVEN a Wikidata Bridge modal
WHEN I change the value in the text field
AND click save
THEN the corresponding value on the repository is changed
GIVEN a logged-in editor on the client
WHEN making an edit through the Wikidata Bridge
THEN the edit is attributed to the same username on the repository (not an IP)
**Acceptance criteria:**
[ ] the edit made in the client is saved on the repository
[ ] the edit is made under the same username on the repository as the one logged-in on the client
[ ] save button as described in figma
[ ] save button is labeled "Publish changes" or "Save changes" based on the client's wgEditSubmitButtonLabelPublish setting
[ ] if an error comes up it will be shown on the modal
**Notes:**
* No need to worry about edit flows yet. Just replace the value unconditionally.
* No need to worry about custom edit summaries. The default ones are fine.
* Adding an edit tag to the edit is part of the next story
