Sample app needs to be rebrand-able

### Describe the bug

The tooling created for Labs is going to be reused for the main toolkit. The sample app that was created is not capable of being rebranded, and is hardcoded as "Toolkit Labs".

```[tasklist]
### Tasks
- [ ] The visual assets
- [ ] Title, subtitle, description and links
- [ ] The app title / package identity
- [ ] Customize top-level pages (home page, about page, others as required)
- [ ] https://github.com/CommunityToolkit/Tooling-Windows-Submodule/issues/70
- [ ] https://github.com/CommunityToolkit/Tooling-Windows-Submodule/issues/77
```

### Help us help you

Yes, but only if others can assist.

Review the sample app and the listed task areas: visual assets, title and descriptive text, links, package identity, and top-level pages. The issue also points to submodule issues 70 and 77, which should be checked before defining the approach. Done means the sample app can be reused with its branding and identity customized rather than hardcoded as "Toolkit Labs".
