Describe the Bug

I imagine you might have this on your radar, but I wanted to create this issue to track the progress. TypeScript 4.9 added a satisfies operator that greatly improves type specificity, but Next.js throws an error when trying to use satisfies:

Support for satisfies specifically was created as an issue that was moved to a Discussion: #40895

It looks like Next.js is currently on @swc/core 1.2.203, and TypeScript 4.8.2, and TypeScript 4.9 support wasn't added until swc 1.3.3. I'm guessing these versions need to be bumped in order to support TypeScript 4.9.

Expected Behavior

Should be able to use TypeScript 4.9.

To Reproduce

Create a project with Typescript 4.9, and attempt to use the satisfies operator.
