Why the version response by /info request mismatch documentation

[sospartan]

Both in doc and swagger spec, it's a { Index: integer } , but it's actual something like:

 {
        "APIVersion": "4.9.3",
        "Version": "4.9.3",
        "GoVersion": "go1.22.1",
        "GitCommit": "",
        "BuiltTime": "Thu Jan  1 00:00:00 1970",
        "Built": 0,
        "OsArch": "linux/arm64",
        "Os": "linux"
    }

which is same as the source code.
