Installing bricks_default_blocks on Drupal 10 causes "The theme bartik does not exist." error.

Problem/Motivation

On install of the bricks_default_blocks submodule, Drupal 10 throws an error because Bartik is gone, and the install is looking for Bartik.

I didn't try the dev version of this module since it looked like it was released at the same time as the last alpha.

Steps to reproduce

* Create a new Drupal 10 instance.
* Try to install bricks_default_blocks.

You will get this error:

The website encountered an unexpected error. Please try again later.

Though, I do think the install at least partially worked. The module shows as enabled, and there is some block configuration available. I'm new to Bricks so I don't know if anything is missing...

Proposed resolution

Don't have a dependency on Bartik.
