Add .ts compatibility to storyshots

[igor-dv]

Issue: #2630

What I did

A quick fix to make ts stories to work well with stoyshots and multiSnapshotWithOptions.
#2517 might revisit the ability to customize stoyshots file names.

Perhaps we should add an example showing typescript usage? if that's not too cumbersome in a monorepo?

All angular examples are actually in typescript, Do you think we need something for react ?

[ndelangen]

No, doesn't seem necessary to me, but if whoever reading this, disagrees, let us know :)
