[Bug]: dynamic import from 'data:' URI

[tbossi]

Version

27.5.1

Steps to reproduce

1. Clone my repo https://github.com/tbossi/jest-bug-data-uri-dynamic-import
2. Run npm test
3. The tests fail

Expected behavior

When running in ESM mode you can leverage dynamic import to load a module from a string by providing a data: URI instead of a file: uri.

For example:

const code = 'export const foo = 123'
const imported = await import(`data:text/javascript;charset=utf-8,${encodeURIComponent(code)}`)
console.log(imported.foo) // Should print 123

Actual behavior

Dynamic import throws an Error instead of importing from data URI.

Additional context

PR welcome! 😀

Code is https://github.com/facebook/jest/blob/60eb4160b5258eed5faf381e0c8ea6662076cc6c/packages/jest-runtime/src/index.ts#L486-L501 & https://github.com/facebook/jest/blob/60eb4160b5258eed5faf381e0c8ea6662076cc6c/packages/jest-runtime/src/index.ts#L1502-L1519

So probably tweak the file:// logic here: https://github.com/facebook/jest/blob/60eb4160b5258eed5faf381e0c8ea6662076cc6c/packages/jest-runtime/src/index.ts#L556-L558
