Issue:
Show host name in repo creation prompts
### Describe the feature or problem you’d like to solve

I'm logged into multiple accounts across multiple hosts. When I want to create a repo, I want to make sure that I'm doing it in the right place. Right now, the `gh repo create` prompts all refer to performing the task "on GitHub". This isn't necessarily _wrong_, but it doesn't tell me which one.

### Proposed solution

I'd like to propose that we replace "on GitHub" to "on <host>" to be clear as to where the action is being performed.


Pull request description:
[gh repo create] Show host name in repo creation prompts
Fixes #8430.

### Tests

```shell
# With default github.com
$ bin/gh repo create
? What would you like to do?  [Use arrows to move, type to filter]
> Create a new repository on github.com from scratch
  Create a new repository on github.com from a template repository
  Push an existing local repository to github.com


# With GH_HOST=ghe.io
$ GH_HOST=ghe.io bin/gh repo create
? What would you like to do?  [Use arrows to move, type to filter]
> Create a new repository on ghe.io from scratch
  Create a new repository on ghe.io from a template repository
  Push an existing local repository to ghe.io
```
