Update dependency @apollo/client to v4 - #239

Error: @apollo/client tried to access rxjs (a peer dependency) but it isn't provided by its ancestors; this makes the require call ambiguous and unsound.

Required package: rxjs (via "rxjs/package.json")
Required by: @apollo/client@virtual:0ece98e85d128302c0e14d819d58ff2a7d4d3a1c3c95743881a3e75a0a129bc418f1243d35c35b946706f0252d9772be3368d02487d79968693211c75bde47c4#npm:4.3.3 (via /home/runner/work/litform/litform/.yarn/__virtual__/@apollo-client-virtual-9c19693f0b/0/cache/@apollo-client-npm-4.3.3-57b490ddbe-7f05fa72fd.zip/node_modules/@apollo/client/core/ApolloClient.js)
