[file_selector] Update Pigeon in Android implementation (#10126)

Updates `file_selector_android` to Pigeon 26.x.

Fixes a latent bug in pigeons/file_selector_api.dart; it had a class that was marked as `implements Exception`; in older versions of Pigeon this was ignored, so was a no-op, but in current versions it triggers the very limited subclassing support, which doesn't allow inheriting from outside the interface definition, and thus generates incorrect code.

## Pre-Review Checklist

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
