Turn on typechecking for text component template in showcase

[natmegs]

:pushpin: Summary

Example of how we can use showcase to check types as a consumer for HDS components. This PR opts into template typechecking for the Text component, and similar opt in could be done for showcase templates displaying any typed HDS components.

2 issues preventing this from being merged:

• Currently there are type failures in the text template since the type of this.model is void, even though route and controller are typed. I must be missing something as these docs indicate the type should be inferred based on route + controller
• Using glint-expect-error to get around the above results in CLI output saying the expect error is unnecessary, but removing it results in a legit type error

@natmegs now that @aklkv PR #2109 has been merged, I think this draft PR can be closed right? (they do the same thing if I'm not wrong).
