Run code snippets in ReindexDocumentationIT #32093
Description
Currently it seems we don't run any of the documentation code snippets in ReindexDocumentationIT.
Test methods don't start with the "test..." prefix, so we don't catch any errors in the documented code snippets other
than compile errors. I think the snippets should be run like in other code documentation tests. However this might
require some additional test setup code. Also I think the api responses require some basic assertions.
Otherwiew we miss errors like the one reported in #32010.
