fixes(spring) add JsonProperty on setter

[antechrestos]

In order to fix #22757, I applied same logic used on java side by #9041

• extract jacksonAnnotation partial template
• extract xmlAccessorAnnotation partial template
• apply jacksonAnnotation and xmlAccessorAnnotation partial templates on both getter and setter

---

Summary by cubic

Add @JsonProperty to generated setter methods in Java Spring models so Jackson maps JSON names correctly, especially for custom or non-standard field names. Regenerates Spring samples to reflect the change and resolve deserialization mismatches (fixes #22757).

• Bug Fixes
  • JavaSpring pojo.mustache: add @JsonProperty on setters when using Jackson, excluding jackson-optional-nullable fields.
  • Regenerated Spring sample models to annotate setters (e.g., fields like "@type", "123-list", names with dashes/spaces).
  • Ensures consistent property name mapping and setter-based deserialization without affecting Optional/JsonNullable behavior.

^{Written for commit 81ab5b7. Summary will update on new commits.}

@wing328 here's the fix I was waiting to push after the merge of #22854

As suggested in the issue #22757 , I applied the fix that already is present on java side; also, I used partial so as not to repeat myself.
