Graphql package version conflict

[milkstork-kevin]

Version of FoalTS: v1 as well as v2

I'm getting this error when I try to do an npm i:

I've tracked this issue down to the fact that the type-graphql package depends on graphql@15 whereas @foal/graphql is still on 14. Is there any reason we couldn't bump @foal/graphql up to v15?

Thank you for you investigation.

@foal/graphql only specifies major versions of graphQL package because the interface of the functions used internally might break between two major versions.

Prior versions of type-graphql were working (ex: 0.17.5) with v14.

I just updated and tested the package so that it can work with v15 starting from v2.9. Until the new version is published, you can still use a prior version of TypeGraphQL to make it work 👍
