build: enable new decorator for swc (#7070)

bs now has migrated to stage 3 decorators. to enable running affine locally with debugging blocksuite, we need to [turn this on](https://swc.rs/docs/configuration/compilation#jsctransformdecoratorversion).

Question:
It seems affine core code already uses stage 3 decorators, however we do not have an issue without this flag since we haven't used class field decorators that uses the `accessor` keyword?
