GHSA-pm3x-jrhh-qcr7 SpiceDB WriteRelationships fails silently if payload is too big

• Go github.com/authzed/spicedb: < 1.45.2 → fixed in 1.45.2

Impact Users who 1. use the exclusion operator somewhere in their authorization schema 1. have configured their SpiceDB server such that `--write-relationships-max-updates-per-call` is bigger than 6500 1. issue calls to WriteRelationships with a large enough number of updates that cause the payload to be bigger than what their datastore allows will 1. receive a successful response from their `WriteRelationships` call, when in reality that call failed, 2. receive incorrect permission check results, if those relationships had to be read to resolve the relation involving the exclusion Patches Upgrade to v.145.2. Workarounds Set `--write-relationships-max-updates-per-call` to `1000`.
