[Bug]: "ExperimentalWarning: The Fetch API is an experimental feature" shown during storybook commands in node v18

[kasperpeulen]

Describe the bug

We use isomorphic-unfetch that will use the actual fetch implementation in node 18.
However, this will cause warnings:

We should probably move to node-fetch, or conditionally use isomorphic-unfetch only when the environment is node 19, where the fetch impl. is stable.

To Reproduce

Start storybook v7 in node 18.

System

@kasperpeulen I wasn't able to reproduce this in a sandbox:

Am I missing something? What node version did you use exactly?

[kasperpeulen]

@tmeasday This only happens in node 18 and (when telemetry enabled I guess).

[kasperpeulen]

Also happens for me in a sandbox when using node 18:

[tmeasday]

@kasperpeulen i was running node 18 (see screenshot) and telemetry was definitely enabled.

Which version of node 18 did you have exactly?

[tmeasday]

Oh, 18.12 I see. I'll try that version

[kasperpeulen]

I can confirm that I don't see this message in next when using node 18.

Crikey!! I just released https://github.com/storybookjs/storybook/releases/tag/v7.0.0-rc.0 containing PR #21497 that references this issue. Upgrade today to the @next NPM tag to try it out!

npx sb@next upgrade --prerelease

[tmeasday]

OK, I see this warning (on older versions) in node 18.12 but not 18.15. I think we should revert, we shouldn't risk making late changes to telemetry for specific minor node versions.
