Unclear compiler error if string used as a path

[Alex Kanunnikov]

Original issue: emberjs/ember.js#19137
Attempt to fix: emberjs/ember.js#19137

But with compiler updates, error migrated to glimmer scope.

Likely should be fixed here: https://github.com/glimmerjs/glimmer-vm/blob/master/packages/@glimmer/syntax/lib/parser/handlebars-node-visitors.ts#L465
