We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Content: Clarify that a domain that appears "available" is not guaranteed
### Story
As an applicant
I want to understand that my requested domain is not guaranteed
so that I can set appropriate expectations for myself and my team.


### Acceptance Criteria
On the ".gov Domain" step in the application process, language appears that clarifies a requested domain is not guaranteed.

### Additional Context
During user testing, most people understood what to input, but it could’ve been more explicit that the domain they entered was not guaranteed, even if available. When prompted, most participants understood the process they would go through to get the domain, but the language could be more explicit.
