Fix build config: revert buildSearchableOptions to tasks block, remove unused Java plugin dep

- Move buildSearchableOptions disable back to tasks block (the extension
  property may not exist in IntelliJ Platform Gradle Plugin 2.3.0)
- Remove bundledPlugin("com.intellij.java") — not used by any source code
- Update foojay-resolver-convention to 1.0.0 (matches JetBrains template)
