[quick_actions] Update Android Pigeon version (#8580)

`quick_actions_android` was still using a very old version of Pigeon; this updates to the current version. The changes are minimal, but this avoids inconsistency with other plugins (e.g., `setup` vs `setUp`), and potential issues with forcing old versions of transitive dependencies shared with `pigeon`.

Also makes some minor code improvements on the Java side that were flagged by the IDE's linter.
