BazelCI breakage due to java8 library desugaring issue in bazel

[ted-xie]

See this BazelCI run for commit 088f922. @bazel_tools//tools/android:desugar_java8_legacy_libs is failing because it still references legacy desugarer flags, even after the default desugar tool in Bazel was switched to D8 in Bazel 6.0.0. This needs to be fixed in Bazel.
