SonarQube Analysis / sonarqube (pull_request) Successful in 5m12s
Promote the `new JsonSerializerOptions { Converters = { ... } }` instance
that `OneTimeSetup` was constructing on each fixture run to a
`private static readonly JsonSerializerOptions _jsonOptions` field, so
the converter list isn't rebuilt per fixture. Strictly cosmetic here
(OneTimeSetup runs once) but it's the change the analyzer wants and the
field is the more idiomatic JsonSerializer pattern.
