## Problem
The `dependency-submission` action disables Isolated Projects for the
dependency-resolution build by passing
`-Dorg.gradle.unsafe.isolated-projects=false`.
Recent Gradle versions have promoted the property to
`org.gradle.isolated-projects`. A build that enables IP via the promoted
property (e.g. `gradle/gradle`, see [this failing
run](https://github.com/gradle/gradle/actions/runs/30357651750/job/90269499556?pr=38402))
is no longer disabled by the unsafe spelling, so the build runs with IP
enabled and fails:
```
Error resolving plugin [id: 'gradlebuild.build-environment']
> Project ':build-logic-settings' cannot access 'Project.tasks' functionality on subprojects via 'allprojects'
```
(`ForceDependencyResolutionPlugin` is not IP-compatible.)
## Fix
Pass both spellings of the property. `-D` system properties that Gradle
does not recognize are silently ignored, so this is safe for all
supported Gradle versions — the action already passes the unsafe
spelling to pre-IP Gradle versions without issue.
