Handle "integer" properly in anyOf error handler

[jdesrosiers]

In #101, we recognized the need for special handling for "integer" in the type error handler, which is a weird special case value for type. @srivastava-diya is working on handling that case properly, but it occurs to me that we do something similar in the anyOf error handler and we aren't handling "integer" properly there either.

Schema:

{
  "anyOf": [
    { "type": "integer" },
    { "type": "boolean" }
  ]
}

Instance:

"foo"

Current Result:

{
  "errors": [
    {
      "message": "Unexpected value ⁨\"foo\"⁩. ⁨Expected a ⁨\"boolean\"⁩.⁩",
      "instanceLocation": "#",
      "schemaLocation": "https://example.com/main#/anyOf"
    }
  ]
}

Expected Result:

{
  "errors": [
    {
      "message": "Unexpected value ⁨\"foo\"⁩. ⁨Expected an ⁨\"integer\" or \"boolean\"⁩.⁩",
      "instanceLocation": "#",
      "schemaLocation": "https://example.com/main#/anyOf"
    }
  ]
}
