Move the uniffi-dart pin back to upstream

The multi-crate codegen fixes (Uniffi-Dart/uniffi-dart#150, #154, #156)
are all merged upstream, so the temporary pin to the contributor fork is
no longer needed. Pin the current upstream main rev, as no release tag
has been cut since v0.2.1.

Upstream codegen now emits ignore_for_file hints and drops unused
imports, but it introduces unused locals in async callback trampolines,
so add unused_local_variable to the generated-code lint ignores.
