Subject: [PATCH] Update immutable to 4.3.8 and enable skipLibCheck

Bump immutable from 4.0.0-rc.12 to the stable 4.3.8 release (top of the 4.x line; stays within the <5.0.0 peer ranges required by @nteract/* and redux-immutable).

immutable 4.3.8 tightened RecordOf<TProps extends Object> to extends object. The third-party @nteract/myths types (pulled in via @nteract/core) pass an unconstrained STATE to RecordOf<STATE>, which tsc rejects. Enable skipLibCheck (standard TS fix) to skip type-checking of node_modules .d.ts files; no effect on emit or our own source.
