fix(deps): pin springdoc-openapi to 2.8.9 for Spring Boot 3.5 compatibility

[wyattwalter]

What

Pins springdoc-openapi-starter-webflux-ui from 2.6.0 to 2.8.9 in app/server/appsmith-server/pom.xml.

Why

With springdoc enabled, GET /v3/docs returned HTTP 500:

java.lang.NoSuchMethodError: org.springframework.web.method.ControllerAdviceBean.<init>(java.lang.Object)
    at org.springdoc.core.service.GenericResponseService...

The server runs Spring Boot 3.5.14 (Spring Framework 6.2), which removed the ControllerAdviceBean(Object) constructor. springdoc 2.6.0 still calls it, so the OpenAPI docs endpoint fails at runtime. Version 2.8.9 is compatible with Spring Framework 6.2 and generates the spec successfully.

Scope

This only makes the OpenAPI docs endpoint functional when enabled. It does not change any defaults:

• Docs stay off by default (springdoc.api-docs.enabled=false, springdoc.swagger-ui.enabled=false unchanged).
• Docs stay authentication-gated — no SecurityConfig / permitAll changes.

The diff is a single dependency-version bump.

Verification

• mvn -pl appsmith-server dependency:tree -Dincludes=org.springdoc resolves 2.8.9.
• mvn -pl appsmith-server -am -DskipTests compile → BUILD SUCCESS.
• Transitive tree is clean (pulls swagger-core-jakarta:2.2.30, swagger-ui:5.21.0 — the expected companions for 2.8.9).

Summary by CodeRabbit

• Chores
  • Updated the OpenAPI documentation component to a newer version, improving compatibility and access to the latest fixes.
