update for kotlin 2.1.0

[chadselph]

When using this plugin with kotlin 2.1.0 and a js project, my build fails with

... [irrelevant stack]

I guess this method was removed in Kotlin 2.1.0; which also causes this PR to fail #138.

It seems like this change is breaking for Kotlin 2.0.x so maybe someone else can find a way to make it work in both.

Thanks for this! Reflection can help making it work with both Kotlin versions simultaneously, but I'd rather keep it simple.

We already had a note about Kotlin vs kotlinx-resources versions in the README:

The latest version targets Kotlin 2.0 and is incompatible with Kotlin 1.9. On 2.0 and above, use the latest version available. On 1.9, use the latest version below v0.9.0.

I'll just turn it into a table. 😄
