Gradle retry plugin retries whole test class instead of single test

[pkazlenka]

Currently, gradle retry plugin retries the whole spock specification instead of single failed test.

Possible ideas how to attempt to fix it:
a) bump plugin version
b) move to spock's @Retry plugin (https://spockframework.org/spock/docs/1.3/extensions.html)
c) fix problem in https://github.com/gradle/test-retry-gradle-plugin
