Change the field label when publishing to existing space

Steps to reproduce:

1. Open a versioned space

2. Publish -> Publish to existing

3. A dialogue comes up, put the cursor in the Space Key field

4. Start typing the space key as the title suggests

Expected result:

• Either the field should be renamed to Space Name

• or the field should also accept space keys

Actual result:

• Only space titles are accepted

• The title of the field and the description contradict each other (see screenshot)
