build: update Gradle to `7.6`

[lukeribchester]

Description

Updated Gradle to version 7.6 by updating the wrapper:

gradle wrapper --gradle-version 7.6

Potential breaking changes

Upgrade to Kotlin 1.7.10

The embedded Kotlin has been updated to Kotlin 1.7.10.

Gradle doesn’t ship with the kotlin-gradle-plugin but the upgrade to 1.7.10 can bring the new version. For example when you use the kotlin-dsl plugin.

The kotlin-gradle-plugin version 1.7.10 changes the type hierarchy of the KotlinCompile task type. It doesn’t extend from AbstractCompile anymore. If you used to select Kotlin compilation tasks by AbstractCompile you need to change that to KotlinCompile.

— Upgrading from 7.5 and earlier
