UpgradePluginVersion fails to upgrade plugins with 'apply false'

[flex-gwanbin]

Description

The UpgradePluginVersion recipe currently fails to upgrade plugin versions when the apply {boolean} clause is present in the plugin declaration.

Current Behavior

When a Gradle plugin is declared with apply false, the recipe does not detect it as a plugin version that should be upgraded:

// Kotlin DSL - Not upgraded
plugins {
    id("com.github.johnrengelman.shadow") version "7.1.0" apply false
}

// Groovy DSL - Not upgraded
plugins {
    id 'com.github.johnrengelman.shadow' version '7.1.0' apply false
}

Expected Behavior

The recipe should upgrade the plugin version regardless of the presence of apply false:

// Should be upgraded to:
plugins {
    id("com.github.johnrengelman.shadow") version "7.1.2" apply false
}

Root Cause

The current implementation in isPluginVersion() only checks the immediate parent of the version() method call for the plugins() method. When apply false is present, the chain becomes:

plugins() -> ... -> apply() -> version()

The method needs to walk up the entire method invocation chain to find plugins().

Environment

• OpenRewrite version: main branch (latest)
• Build tool: Gradle
• DSL: Both Kotlin DSL and Groovy DSL affected
• Recipe: org.openrewrite.gradle.plugins.UpgradePluginVersion

Proposed Solution

Modify isPluginVersion() to walk up the method invocation chain until it finds the plugins() method or reaches the root, rather than only checking the immediate parent.

I have a fix ready and will submit a PR shortly with test coverage for both Kotlin DSL and Groovy DSL cases.
