Worktrees attached to bare repo don't work

I have a bare repository and several worktrees attached to it. That was working fine until recent update. Now when I try virtually any git command like `git status` in any attached worktree, or even in a new one, it prints `fatal: this operation must be run in a work tree`. The workaround is simply `git config --worktree --add core.bare false` in each worktree.

I have git version 2.28.0 on Void Linux (musl, amd64).
