Update FlatBuffers to 24.3.6-1 (fix cannot set temporal layer 0)

[ibc]

• Due to an issue in Flatbuffers (https://github.com/google/flatbuffers/issues/8245) when we call consumer.setPreferredLayers() with temporalLayer: 0 (or transport.consume() with temporalLayer: 0 in preferredLayers), we are NOT passing temporalLayer to the worker so it selects the highest available temporal layer instead.
• This PR tests that use case in both Node and Rust, and tests should fail (only in Node) until the FlatBuffers issue is resolved.
• And the issue in FlatBuffers was fixed long ago (https://github.com/google/flatbuffers/issues/8245) but the release happened now. And here the new version in Meson WrapDB: https://github.com/mesonbuild/wrapdb/pull/1441

FlatBuffers 24.3.6 (with the fix) has been released. The NPM version is already available. Ongoing work in Meson WrapDB to update FlatBuffers there: https://github.com/mesonbuild/wrapdb/pull/1441
