ghcup's support of HLS broke CI

My CI would build new docker images when the dockerfile changed. Recent ghcup changed its behavior to require user input where previously none was needed:

Ideally this behavior would first detect if there is a tty, or if not then off by default, or if not then a flag. Are one of these options on the table?
