[Bug]: Marshaling Array type in Lua runtime

[Isan-Rivkin]

What happened?

What actually happened, including error codes if applies.

Steps to Reproduce:

1. create an array in a lua script test.lua

local arr = {
    {
        A = "a" 
    }
}

2. call lakeFS action or directly via ./lakefs lua run test.lua
3. Runtime error: runtime error: invalid key to 'next'

The runtime error comes from go-lua source code because we don't recognize it's an array in isArray.

Expected behavior

Marshaling arrays should work.
