Having `@types/node` in dependency causes unexpected upstream issues.

[Gijsdeman]

A concrete example:

jest-config@30.2.0:
peerDependencies:
  '@types/node': '*'

Thus, when having @playform/pipe as (indirect) dependency, a mismatch in @types/node can occur. Moving the dependency to peer dependencies resolves this conflict while still indicating that this version of @types/node must be installed.
