Versioning plugin + Dokka v2 Gradle plugin false .DS_Store warning

[jeffdgr8]

Describe the bug
Using the versioning plugin with the Dokka v2 Gradle plugin produces the warning:

[:dokkaGeneratePublicationHtml] Failed to find versions file named version.json in /{olderVersionsDir}/.DS_Store

Expected behaviour
No warning should be output. .DS_Store (and probably any non-directory file) should be ignored.

To Reproduce
Run the :dokkaGenerate task with a .DS_Store file in the olderVersionsDir directory.

Dokka configuration
Configuration of dokka used to reproduce the bug

dependencies {
    dokkaPlugin(libs.dokka.versioning)
}

tasks.dokkaGeneratePublicationHtml {
    dokka.pluginsConfiguration.versioning {
        olderVersionsDir = projectDir.resolve("docs/older")
        // ...
    }
}

Installation

• Operating system: macOS
• Build tool: Gradle v8.11.1
• Dokka version: 2.0.0

Additional context
Reproducible with my library, Kotbase.
