Revert "Update `swc_core` to `v0.100.6` (#68560)" (#68978)
### What?
Revert swc_core upgrade, as it has a bug related to `styled_jsx`
transform.
Wasm plugin version runs after the TypeScript pass so it works, but
custom transform (next-swc) runs before the typescript pass so it
breaks.
### Why?
It broke some apps.
### How?
