Invalid tables spec causes deserialization errors in the tables client.

[Leptopoda]

The tables specs state that the result of a api1.indexTableRowsSimple request returns a List<Strings>

But it actually returns a List<List<String>>:

[
  [
    "What",
    "How to do",
    "Ease of use",
    "Done"
  ],
  [
    "Open the tables app",
    "Click on tables icon in the menu bar.",
    5,
    "true"
  ],
  [
    "Add your first row",
    "Just click on \"new row\" and enter some data inside of the form. At the end click on the bottom \"save\".",
    5,
    "false"
  ],
  [
    "Edit a row",
    "Hover the mouse over a row you want to edit. Click on the pen on the right side. Maybe you want to add a \"done\" status to this row.",
    5,
    "false"
  ],
  [
    "Add a new column",
    "You can add, remove and adjust columns as you need it. Click on the three-dot-menu on the upper right of this table and choose \"create column\". Fill in the data you want, at least a title and column type.",
    4,
    "false"
  ],
  [
    "Read the docs",
    "If you want to go through the documentation, this can be found here: https:\\/\\/github.com\\/nextcloud\\/tables\\/wiki",
    3,
    "false"
  ]
]

I don't think this is an issue in the openapi-extractor, as the typing of the relevant php code is also referring to a string[].
Opening an issue upstream to hopefully get it fixed soon.
https://github.com/nextcloud/tables/blob/5cc780ce4260c262e3b733f5cb9d7959a9262938/lib/Controller/Api1Controller.php#L1032-L1060

We might be able to patch the spec for now, but I'm not sure how many endpoints are affected by this issue.
