Theming: Re-export correct bundled file

[IanVS]

Issue:

This might fix #17916.

When trying to use @storybook/theming with the latest storybook 6.5.0-alpha.62, in the mealdrop repo, I got errors like:

ERROR in ./node_modules/@storybook/theming/create.js 2:0-34
Module not found: Error: Can't resolve './dist/esm/create' in '/Users/ianvs/code/storybook-benchmarks/mealdrop/node_modules/@storybook/theming'
resolve './dist/esm/create' in '/Users/ianvs/code/storybook-benchmarks/mealdrop/node_modules/@storybook/theming'

What I did

I found that @storybook/theming/create.js tries to re-export from ./dist/esm/create, which no longer exists (after #17000, I think). So, I changed the path to just ./dist/esm, and found that this indeed solves my error.

cc/ @yannbf, since it looks like you might have hit this as well, in yannbf/mealdrop@c973a55, since you renamed the manager file, presumably to avoid the problem.

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?
