opentelemetry-instrumentation-vertexai 2.2b0

[github-actions[bot]]

• Fix overwritten log attributes in vertexai instrumentation (#3925)
• Add the GEN_AI_OUTPUT_TYPE, GEN_AI_REQUEST_CHOICE_COUNT and GEN_AI_REQUEST_SEED sem conv request attributes to events/spans generated in the stable instrumentation. This was added pre sem conv 1.36 so it should be in the stable instrumentation. See (#4011).
