Bump built_value from 8.1.4 to 8.4.1 in /jsonexample

[dependabot]

Bumps built_value from 8.1.4 to 8.4.1.

Release notes

Sourced from built_value's releases.

Bump version of analyzer

• Bump version of analyzer.

Custom builder improvements; enum improvement

• Fix custom builders in null safe code: allow nested builder fields to be nullable.
• Improve custom builders for null safe code: allow abstract setter/getter pairs instead of fields. This allows nested builders to have a setter that accepts null and a getter that guarantees not to return null, which is what auto instantiation of nested builders already provides.
• Allow use of super field initialization in EnumClass.

Fix codegen for generic bounds

• Fix erroneously generated null check for fields with generic bounds.

Null safe built_value_test

• Migrate built_value_test to null safety.

Generator fixes, ignore lint

• Fix generation support for optional generic bounds, e.g. class Foo<T extends Object?>.
• Fix generation for classes with names starting $.
• Ignore lint unnecessary_lambdas in generated code.

Generator improvements

• Change generated build methods to return only public types, creating _build methods that return the generated impl types. This means dartdoc will no longer reference the generated types.
• Ignore the no_leading_underscores_for_local_identifiers lint in generated code.
• Migrated built_value_generator to null safety. This is purely an internal change, the generator can still generate legacy code as and when needed.

Fix serializer generation corner case

• Bug fix: fix a corner case with generics that had incorrect serializer generation.

Fix build warning

• Bug fix: remove a print from the enum generator.

Fix deps

• Fix deps: allow built_value_generator to use built_value 8.2.0.

Generator improvements for lints, bump analyzer

• Allow writing final parameters in EnumClass constructor and valueOf method.
• Make generator output additional explicit null checks so the generated code complies with the cast_nullable_to_non_nullable lint.
• Bump version of analyzer.
