feat(treesitter): support query table in treesitter-textobjects mappings (#6736)

## Description

<!-- Describe the big picture of your changes to communicate to the
maintainers
  why we should accept this pull request. -->

`treesitter-textobjects` mappings accept a table query (for the "move"
mappings, at least, I haven't checked the others). Currently, in
LazyVim, using a table causes an error due to the assumption that
`query` is a string in the `config` function that creates the keymap
description. This PR adds a simple loop to gather the queries from a
table and join them with "or" in the description.

Here is an example config and the resulting error. Everything works as
expected with the PR and string (single) queries still behave as
expected.

```lua
  {
    "nvim-treesitter/nvim-treesitter-textobjects",
    opts = {
      move = {
        keys = {
          goto_next_start = { ["]j"] = { "@function.outer", "@class.outer" } },
          goto_next_end = { ["]J"] = { "@function.outer", "@class.outer" } },
          goto_previous_start = { ["[j"] = { "@function.outer", "@class.outer" } },
          goto_previous_end = { ["[J"] = { "@function.outer", "@class.outer" } },
        },
      },
    },
  }
```

```lua
