fix: include publishing docs in assemble

[marandaneto]

💡 Motivation and Context

The posthog 6.29.2 release failed while creating its Javadoc artifact. Three Dokka dependencies had been removed from the Gradle lockfiles for posthog and posthog-server. The regular PR build did not create the published documentation artifacts, so it did not resolve those dependencies or catch the incomplete lockfiles.

This restores the missing lock entries. It also adds the Javadoc and HTML documentation jars to assemble for posthog, posthog-server, and posthog-android-gradle-plugin. The existing make compile CI step now creates the same documentation artifacts used during publishing and fails if their dependency locks are incomplete.

No changeset is included because this does not change SDK code or package behavior.

💚 How did you test it?

• make compile
• make updateLocks
• make checkFormat
• make dryReleaseCore
• make dryReleaseServer
• make dryReleaseAndroid
• make dryReleaseAndroidPlugin
• Removed the three Dokka entries locally and verified that ./gradlew :posthog:assemble --rerun-tasks failed with the same missing-lock error as the release
• git diff --check

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

If releasing new changes

• Ran pnpm changeset to generate a changeset file

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Pi coding agent investigated the failed release logs and implemented the fix in a dedicated worktree. We chose to make published documentation part of each relevant module's normal assembly instead of adding special cases to the root Makefile or CI workflow. The final autoreview was skipped at the human driver's request.
