Subject: [PATCH v2 4/4] t-reftable-readwrite: add test for known error

From: Chandra Pratap <[email-masked]>
Date: Fri, 9 Aug 2024 16:35:44 +0530

When using reftable_writer_add_ref() to add a ref record to a
reftable writer, The update_index of the ref record must be within
the limits set by reftable_writer_set_limits(), or REFTABLE_API_ERROR
is returned. This scenario is currently left untested. Add a test
case for the same.
