fix(docs) Temporary disable gh-pages javadoc generation

[markushi]

📜 Description

As

sentry-java/build.gradle.kts

Line 267 in 8295b2f

classpath += javadocTask.classpath

mangles the classpath.

As far as I can see this is only used for the gh-pages branch docs: https://getsentry.github.io/sentry-java/

Note: This is a temporary solution, we should apply a proper fix in the long run.
