Table does not accept valuePath with dots

When trying to render the following table:

  columns = [
    {
      name: "id",
      valuePath: "id",
    },
    {
      name: "value path with dot",
      valuePath: "a.b",
    },
  ];

  rows = [
    { id: 0, "a.b": 2 },
    { id: 1, "a.b": 3 },
  ];

<EmberTable as |t|>
    <t.head @columns={{this.columns}} />

    <t.body @rows={{this.rows}} />
 </EmberTable>

It does not render the values from the column that has a dot (.) on the value path

I don't know if this should actually be fixed, but, if not, we can add this on the documentation saying that those are not supported.

Ember Version: 3.17.0 (i've also tested with 3.22 and the same problem happens)
EmberTable Version: 3.0.1

Start by reproducing the example from the issue with Ember 3.17 or 3.22 and EmberTable 3.0.1, then trace how the table resolves valuePath for row values. Done means either dotted keys render correctly or the limitation is documented clearly.
