Incorrect immer peer dependency

[ambar-arkin]

Immer peer dependency is set to >=2 https://github.com/immerjs/use-immer/blob/b07fdfcefccfc7ff4252d52d58493d443a63d4c2/package.json#L43

But the library depends on freeze function which is only available in >=8. This causes error when using with 2.x version:

Error: Uncaught [TypeError: e.freeze is not a function]

Can immer 2.x still be supported by conditionally freezing only if the function exists?
