Don't fail gradle sync if TargetFormat.AppImage is used on macOS

[m-sasha]

Currently, gradle sync fails on macOS if TargetFormat.AppImage is present in targetFormats.
Note that this PR removes the check entirely, as the list of target formats should not be validated at gradle sync.
There is no corresponding check for e.g. TargetFormat.Dmg on Windows.

Testing

No testing needed.

@terrakok Can you look and say why this fails?

The failures are:

ResourcesTest > cocoapodsIosXCFrameworkResources(kotlin=2.2.0-Beta1, gradle=8.7, agp=8.6.0) FAILED
    org.gradle.testkit.runner.UnexpectedBuildFailure at ResourcesTest.kt:876

and

ResourcesTest > xcframeworkResources(kotlin=2.2.0-Beta1, gradle=8.7, agp=8.6.0) FAILED
    org.gradle.testkit.runner.UnexpectedBuildFailure at ResourcesTest.kt:762

Try to rebase on the fresh master.

Cause 1: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find org.jetbrains.kotlin:compose-compiler-gradle-plugin:2.2.0-Beta2-1

the version was deleted because it is a temporary dev build. I already updated the version in #5330

Try to rebase on the fresh master.

Done, thanks.

@terrakok Now it's failing at

ResourcesTest > testFinalArtefacts(kotlin=2.2.0-Beta1, gradle=8.13, agp=8.9.0) FAILED
    java.io.IOException at ForEachOps.java:183

[terrakok]
