Tech: migrate to es version of lodash

migrating to es version of lodash (manager)

[valentinpalkovic]

@ndelangen Could you quickly compare the bundle sizes and find out whether tree-shaking really works? As mentioned, with our current tsup config tree-shaking might be broken.

[ndelangen]

that seems important, but not really super related to this PR? @valentinpalkovic

[valentinpalkovic]

I would say it is important, in a sense, that we potentially increase the bundle size of the manager quite a lot. But if we do not care that much about it, I would agree with you, that my comment is unrelated to this PR.

[valentinpalkovic]

So maybe we should first make sure that tsup tree-shakes properly (maybe it already does) and then switch out lodash and other packages by their ES counterparts and adjust the imports.

[IanVS]

I agree with @valentinpalkovic. I think we've been working hard to bring down the installation size of storybook, so blowing it up with all of lodash would be a step backwards, if it's not tree-shaking properly.

[ndelangen]

Ok, I'll investigate
