Webpack cannot resolve process in storybook 6.4.13

[jackw]

Describe the bug

Whilst attempting to bump Storybook from 6.4.9 to 6.4.13 Webpack build errors are occurring stating that process/browser.js cannot be resolved. The repo in question is using the storybook-webpack5 builders, yarn Pnp and a custom webpack config.

To Reproduce
I apologise for not creating a specific reproduction but I have an open PR that bumps the repo to 6.4.13 but had to apply changes in this commit for storybook to run locally without issue.

Additional context
I'm guessing it's related to this PR that was included in the 6.4.13 release.

That hasn't been patched to 6.4 yet. If you upgrade to 6.5-alpha does that fix things?

npx sb upgrade --prerelease 

Let me know and I'll patch it back

Ah ok, wasn't aware it hadn't been patched in 6.4 yet. I took a look at https://github.com/storybookjs/storybook/releases/tag/v6.4.13 where that PR is mentioned. 🤔

Turns out I linked the wrong PR. I meant to link to #17213.

Will take 6.5-alpha for a spin shortly and get back to you. Appreciate the quick response @shilman. 👍

It most certainly does! 🥳

Removing the SB config changes made in my PR that replace ProvidePlugin in webpackFinal and managerWebpack then running npx sb upgrade --prerelease works like a charm (once I fix a couple of yarn PnP related peer dependency issues).

Closing this as I've now bumped to storybook v6.4.15 and it's working as expected. Thanks @shilman!
