fix(testing): handle snapshot filepaths (#3282)

this commit updates the testing regex in our jest base configuration to
handle files such as testing snapshots - those that contain 'spec.ts'
(or a similarly acceptable file extension for tests), but do not end
with that extension. For example, `my-component.test.ts.snap`

this fixes a regression introduced in cf42114
