Release Apache Sling GraphQL Core 0.0.18

[Andreas Schaefer]

Hi

I created a new release of GraphQL Core v 0.0.18 and put it up to a vote but so 
far nobody responded.

This is an important release for AEM to fix a security issue in 
graphql-java:https://nvd.nist.gov/vuln/detail/CVE-2022-37734

Thanks - Andy
