Sorry, something went wrong.
This PR adds the jsx-runtime and jsx-dev-runtime modules for the JSX Babel Plugin. WWW still relies on jsx/jsxs/jsxDEV from the "react" module, so once we refactor the code to point to the runtime modules we will remove jsx/jsxs/jsxDEV from the "react" module.

PR Summary
This PR continues the implementation of jsx-runtime and jsx-dev-runtime modules for the new JSX Babel Plugin. The key changes focus on:
- Modified
packages/react/src/ReactDebugCurrentFrame.jsto addsetCurrentlyValidatingElementmethod for debugging - Updated
packages/react/src/ReactElementValidator.jsby removing JSX validation functions - Adjusted
scripts/rollup/forks.jsto support new JSX runtime modules - Added 'react/jsx-dev-runtime' to
importSideEffectsinscripts/rollup/modules.js
These changes further refine the JSX handling in React, improving performance and preparing for future optimizations. The modifications appear consistent with the PR's goals of implementing the new JSX transform while maintaining backwards compatibility.

logic: The __DEV__ check here is redundant since the entire block is already within an if (__DEV__) condition.

logic: The jsx function doesn't handle the __self and __source props, which are present in the ReactElement function. This might lead to inconsistencies.

logic: This warning is only called in jsxDEV but not in jsx. Consider if it should also be added to the jsx function for consistency.
