Rather than doing this, can you just manually set minSdk = 24 in the build.gradle.kts? I think the only place we reference libs.versions.android.sdk.min from the android-sdk-min version in the versionCatalogs is in the app's build.gradle.kts, so I don't think there is any point in overriding it at the version catalog level (for that matter, I wonder why we even bother setting it at all in the versionCatalogs, but we're stuck with it now since all the pre-existing app build.gradle.kts files are referencing it).
