enhance: Bump milvus & proto version to v2.6.6

[congqixia]

[sre-ci-robot]

[ci-v2-notice] Notice: We are gradually rolling out the new ci-v2 system.

• Legacy CI jobs remain unaffected, you can just ignore ci-v2 if you don't want to run it.
• Additional "ci-v2/*" checkers will run for this PR to ensure the new ci-v2 system is working as expected.
• For tests that exist in both v1 and v2, passing in either system is considered PASS.

To rerun ci-v2 checks, comment with:

• /ci-rerun-code-check // for ci-v2/code-check
• /ci-rerun-build // for ci-v2/build
• /ci-rerun-ut-integration // for ci-v2/ut-integration
• /ci-rerun-ut-go // for ci-v2/ut-go
• /ci-rerun-ut-cpp // for ci-v2/ut-cpp
• /ci-rerun-ut // for all ci-v2/ut-integration, ci-v2/ut-go, ci-v2/ut-cpp
• /ci-rerun-e2e-arm // for ci-v2/e2e-arm
