Describe the Bug

Latest next.js + babel not supported Type-only import specifiers because version of @babel/core for now is 7.15.0

next.js/packages/next/package.json

Line 99 in b2045c7

"@babel/core": "7.15.0",

For my case I can't drop babel, but I need this feature, because it works without babel with typescript 4.5+.

Expected Behavior

Type-only import specifiers are supported

To Reproduce

Just run any project with next.js and babel and try

// TypeScript 4.5
import { type Foo, fooInstance } from "my-module";

This code will give you an error
Unexpected token, expected ","

Without babel, all works fine.

Done. I don't know if that small change is enough :)
