Fix Windows start scripts classpath

[EmreeAltunn]

This PR fixes startScripts generation on Windows.

Before this change, running:

./gradlew.bat :allure-commandline:startScripts

failed with:

Illegal char <*> at index ... src/lib/*

The previous classpath used a wildcard path with files(...), which can be interpreted as an invalid path on Windows because of the * character.

Changes

Replaced the wildcard path with fileTree("src/lib") while keeping src/lib/config on the classpath.

Verification

Verified on Windows with:

./gradlew.bat :allure-commandline:startScripts

Result:

BUILD SUCCESSFUL
