fix(mongodb): replace deprecated DecodeBytes

[Fontinalis]

What changed

Replace the deprecated SingleResult.DecodeBytes call with SingleResult.Decode.

This keeps the MongoDB test compatible with both the current driver version and v1.17.7, where DecodeBytes causes a staticcheck failure. It unblocks #1429.

Testing

go test ./database/mongodb -run '^$'

[Copilot]

🟢 Approval recommended

The change is a direct, equivalent replacement of a deprecated API with the supported decode path and appears consistent with the existing isMaster struct decoding logic.

Pull request overview

This PR updates the MongoDB replica-set initialization helper in the MongoDB test suite to avoid using the deprecated mongo.SingleResult.DecodeBytes, improving compatibility with newer mongo-driver versions (and removing a staticcheck failure in v1.17.7).

Changes:

• Replace SingleResult.DecodeBytes + bson.Unmarshal with a single SingleResult.Decode(&status) call in waitForReplicaInit.

File summaries

File	Description
database/mongodb/mongodb_test.go	Simplifies RunCommand(...).Decode handling by decoding directly into the isMaster struct instead of decoding raw bytes and unmarshalling.
