[infra] Ignore analyzer issues in CI (flutter#2271)

35e984f migrated some deprecated analyzer warnings to the newer
alternatives. These created some failures in unrelated plugins based on
the warnings being slightly different.

Added `ignore`s for now to turn CI green again as soon as possible. The
previous analysis options really should not be used and the majority of
the patch was unrelated, so I prefer ignoring specific already failing cases
to reverting in this case. Including an `analysis_options.yaml` file with
deprecated analyzer rules causes analyzer failures in the including package,
so that patch can't be landed in a way that prevents regressions
without updated rules.
