createTrackerLink from @openreplay/tracker-graphql returns incompatible type

[andreialecu]

Ref: https://github.com/openreplay/openreplay/blob/5700a16a945797f002f778fa7ebf95a07c79ab98/tracker/tracker-graphql/src/apolloMiddleware.ts#L5-L11

@apollo/client exports a type for RequestHandler which is incompatible with the one exported by @openreplay/tracker-graphql, resulting in TS errors when trying to assign the result of tracker.use to a variable of type RequestHandler

Type '(operation: Operation, forward: NextLink) => Observable<unknown>' is not assignable to type 'RequestHandler'.
  Types of parameters 'forward' and 'forward' are incompatible.
    Types of parameters 'operation' and 'operation' are incompatible.
      Type 'Operation' is missing the following properties from type 'Operation': setContext, getContextts(2322)

repro:

import type { RequestHandler } from '@apollo/client/core';

class AnalyticsService {
  trackerLink: RequestHandler | undefined = undefined;

  init() {
    this.trackerLink = tracker.use(createTrackerLink());
  }
}

The type from @apollo/client should be used instead. Also @apollo/client should probably be an optional peer dependency in package.json, see: https://yarnpkg.com/configuration/manifest#peerDependenciesMeta.optional
