Update Compose Multiplatform compatibility matrix

[compose2pdf-bot]

Auto-detected new Compose Multiplatform versions from Maven Central.

Updated matrix:

{
  "versions": [
    {
      "compose-version": "1.10.3",
      "kotlin-version": "2.4.0"
    },
    {
      "compose-version": "1.11.1",
      "kotlin-version": "2.4.0"
    },
    {
      "compose-version": "1.12.0-alpha01",
      "kotlin-version": "2.4.0"
    }
  ]
}

The compatibility CI will run on this PR to verify all versions build and pass tests.
If a version fails, adjust its kotlin-version in .github/compose-versions.json before merging.
