The classy base theme is still referred in some files.

Problem/Motivation

After installing the latest dev version of this theme on a Drupal 10 system, I discovered that there are still some references to the base classy theme that was used in the Drupal 9 version.
These are comment.html.twig and status-messages.html.twig.

Steps to reproduce

Switch theme to Olivero
Unstall Danland theme
Install latest dev version of Danland theme
Switch to Danland theme and make it "standard"
Remove the old Classy and Stable themes because Danland is now based on Stable9
I'm getting some PHP errors in the log that still reference Classy code

Proposed resolution

Remaining tasks

User interface changes

API changes
