remove classic runtime for react

[afkcodes]

the classic jsx runtime expects react import to be present in every file, but not every page or component is using something directly from react, so its unused, some of the editor has settings to remove unused imports this is where it breaks the application as it removes the unused react import.

Sadly this still seems to cause the following error in automatic mode (mentionned in the comment above the option):

TypeError: jsxDEV is not a function

There probably is another solution , but I haven't found it yet.

The error only occurs for the combination React + Vercel + HatTip.
I'll just activate the "classic" option for this use case then.

i guess there is no role of vercel here, probably hatTip might be the one that might be erroring out. but needs to be checked
