Allow files without .stories.tsx to be indexed

[Tibblist]

Is your feature request related to a problem? Please describe.

There is poor documentation around experimental_indexers to create titles for files without .stories in them

Describe the solution you'd like

Better documentation/examples for simple use cases or a default indexer that can handle simple filenames better like just replacing .stories with another word

Describe alternatives you've considered
