Stop using deprecated AbstractArchiveTask.archivePath in Gradle build

This commit addresses the following warning in the build.

The AbstractArchiveTask.archivePath property has been deprecated. This
is scheduled to be removed in Gradle 9.0. Please use the archiveFile
property instead. See
https://docs.gradle.org/8.1.1/dsl/org.gradle.api.tasks.bundling.AbstractArchiveTask.html#org.gradle.api.tasks.bundling.AbstractArchiveTask:archivePath
for more details.

Closes gh-30697
