TT1 Blocks: Fix or remove front page template

[fklein-lu]

The TT1 has a front-page.html template that only shows the post content.

There are two main issues with this:

1. The original theme does not seem to have a front page template.
2. But front page templates need to respect the reading settings. This means that if the homepage is set to display posts, a list of posts should be displayed. So there most be a loop and a blog display here.

This need to be solved with the query block(?) up streams, and the theme can be adjusted afterwards.

No, the template needs to be fixed. Because there's no Query Block in there.

Add a Query Block to the template, have it inherit the Main Query, and it all will work as expected.

Or better yet remove the template, since the original Twenty Twenty-One theme doesn't have a front page template either, and TT1 is supposed to be a block version of that theme.
