<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->
currently, because it requires to sign locally, so i thought run command
like
`:project-graph:publishToMavenLocal -x
:project-graph:signNxProjectGraphPluginPluginMarkerMavenPublication -x
:project-graph:signPluginMavenPublication -x
:project-graph:publishNxProjectGraphPluginPluginMarkerMavenPublicationToMavenLocal
-x :project-graph:publishPluginMavenPublicationToMavenLocal` would
publish the plugin locally, but it actually does not. it does not throw
an error, but does not do anything at all.
so for e2e tests, it is actually pulling the latest published gradle
plugin from maven rather than test local code, hence the e2e errors.

also, currently project graph build for java version 21, we change it to
java 17 to be used by ocean repo.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
change the command to `./gradlew :project-graph:publishToMavenLocal
-PskipSign=true` and not apply signing when skip sign is true, so this
should be able to publish plugin to local repository.

work with java 17
