The flag is internal in Spark 4, so I propose to treat it as false(default)
```
val LEGACY_COMPLEX_TYPES_TO_STRING =
buildConf("spark.sql.legacy.castComplexTypesToString.enabled")
.internal()
.doc("When true, maps and structs are wrapped by [] in casting to
strings, and " +
"NULL elements of structs/maps/arrays will be omitted while
converting to strings. " +
"Otherwise, if this is false, which is the default, maps and structs
are wrapped by {}, " +
"and NULL elements will be converted to \"null\".")
.version("3.1.0")
.booleanConf
.createWithDefault(false)
```
And fallback to Spark if this flag is true
