fix(template-no-attrs-in-components): support co-located templates, broaden test coverage

Add /components/ to the path gate regex to catch Octane co-located
templates (app/components/foo.hbs) which the previous pattern missed
(cf. ember-template-lint#1445).

Add invalid test cases for attrs in attribute value, block helper, and
hash pair positions, and for the co-located path pattern.
