JSON:API resource schemas were emitted with properties but no type, so a
consumer validating against them could not tell the schema describes an object.

The test, on 5.0 without the two-line fix:

1) ApiPlatform\JsonApi\Tests\JsonSchema\SchemaFactoryTest::testHasRootDefinitionKeyBuildSchema
Failed asserting that null is identical to 'object'.
2) ApiPlatform\JsonApi\Tests\JsonSchema\SchemaFactoryTest::testPostInputSchemaDoesNotRequireId
Failed asserting that null is identical to 'object'.
3) ApiPlatform\JsonApi\Tests\JsonSchema\SchemaFactoryTest::testErrorSchemaIsAnObject
Failed asserting that null is identical to 'object'.

Tests: 11, Assertions: 50, Failures: 3.

With the fix:

OK (11 tests, 56 assertions)

src/JsonApi/Tests/JsonSchema/SchemaFactoryTest.php carries the assertions;
testErrorSchemaIsAnObject is new and covers the error schema path from #8701.
