Restore micronaut-jackson-databind for grails-forge-web-netty JSON runtime

After PR #15647 + #15648 fixed dockerBuildNative + Cloud Run startup
for the analytics service, both Forge deploy workflows finally
finished green and pushed `next.grails.org` (8.0.0-M1 hotfix branch)
and `prev-snapshot.grails.org` (8.0.x) revisions live. start.grails.org
still does not list 8.0.0-M1 / 8.0-SNAPSHOT in the Grails Version
selector, though, because both backends return:

  $ curl -i -H 'Origin: https://start.grails.org' https://next.grails.org/versions
  HTTP/1.1 500 Internal Server Error
  Content-Type: application/json
  ...
  {"_embedded":{"errors":[{"message":"Internal Server Error: Error
   encoding object [org.grails.forge.api.VersionDTO@..] to JSON: No
   serializable introspection present for type VersionDTO. Consider
   adding Serdeable.Serializable annotate to type VersionDTO."}]},
   "message":"Internal Server Error"}

Reproduced locally (`docker run grails-forge-local:web-netty` against
the GraalVM Community 21.0.2-ol9 native image with CORS_ALLOWED_ORIGIN
set, then `curl -H 'Origin: https://start.grails.org' /versions`) -
identical 500.

Root cause: PR #15365 review feedback (commit e1f3013070,
"Address PR review feedback: telemetry override, forge BOM
adoption, publish plugin bump") swapped grails-forge-web-netty's
runtime JSON dependency:

  -    runtimeOnly 'io.micronaut:micronaut-jackson-databind'
  +    runtimeOnly 'io.micronaut.serde:micronaut-serde-jackson'

with the rationale that "the forge stack is a Micronaut 4 serde-
jackson application; the legacy jackson-databind runtime was a
copy-paste from an earlier generator template". That is not yet
true: every DTO returned by the Forge controllers
(VersionDTO, ApplicationTypeDTO, FeatureDTO, FeatureList,
SelectOptionsDTO, GormImplDTO, JdkVersionDTO, LanguageDTO,
ServletImplDTO, DevelopmentReloadingDTO, GitHubCreateDTO,
PreviewDTO, ApplicationTypeList, LinkDTO, the abstract Linkable
parent, ...) carries `@Introspected` only - none of them are
`@Serdeable` or registered via `@SerdeImport`. Micronaut Serde
correctly rejects @Introspected-only classes at runtime, while
Micronaut Jackson Databind serialises them via Jackson + bean
introspection. The mismatch turns every JSON endpoint behind
next.grails.org and prev-snapshot.grails.org into a 500, which
is why Forge UI's `versions` fetch is empty for those backends
and 8.0.0-M1 is missing from the start.grails.org Grails Version
selector.

The other Forge modules (forge-api tests, forge-core, analytics-
postgres) all still use micronaut-jackson-databind; web-netty
was the only inconsistency. Restore web-netty to
micronaut-jackson-databind so the runtime matches the rest of the
forge stack and the existing @Introspected DTOs serialise. A
proper end-to-end Serde migration belongs in a separate PR that
also annotates every Forge DTO with @Serdeable / @SerdeImport.

Verified locally on Docker 29.3.0 with the same Java 21 GraalVM
Community 21.0.2-ol9 native-image container the deploy workflows
use:

  $ curl -i -H 'Origin: https://start.grails.org' http://localhost:18080/versions
  HTTP/1.1 200 OK
  Access-Control-Allow-Origin: https://start.grails.org
  Vary: Origin
  Access-Control-Allow-Credentials: true
  content-type: application/json
  ...
  {"_links":{"self":{"href":"http://.../versions","templated":false}},
   "versions":{...,"grails.version":"8.0.0-M1",...}}

  $ curl -i -H 'Origin: https://start.grails.org' http://localhost:18080/select-options
  HTTP/1.1 200 OK
  Access-Control-Allow-Origin: https://start.grails.org
  ...

Endpoints serve JSON cleanly; CORS allow-origin header is present;
the start.grails.org Grails Version selector will pick up 8.0.0-M1
once next.grails.org is redeployed from this commit.
