[JENKINS-31159] Release post build steps for Matrix project cannot be set from UI

Assigning release build steps to After failed or successful release build and all matrix configurations is impossible from Jelly UI because of code duplication in src/main/resources/hudson/plugins/release/ReleaseWrapper/config.jelly 2.5.3:

Line 105

		    

		    "attach-previous">${%After failed or successful release build}

		    "postBuildSteps" hasHeader="true"

		     descriptors="${h2.getBuildSteps(it)}"

		     items="${instance.postBuildSteps}"

		     addCaption="${%Add release step}"/>

is duplicated at line 160:

		    

		    "attach-previous">${%After failed or successful release build and all matrix configurations}

		    "postBuildSteps" hasHeader="true"

		     descriptors="${h2.getBuildSteps(it)}"

		     items="${instance.postBuildSteps}"

		     addCaption="${%Add release step}"/>

whereas it should use postMatrixBuildSteps instead of postBuildSteps.

This results in the post build steps steps to be duplicated each time the page is saved.

The only workaround is NOT to rely on Jenkins Jelly UI to configure such job (XML editing / Jenkins API).

```
Jenkins 1.619

release-plugin 2.5.3
```

Start with src/main/resources/hudson/plugins/release/ReleaseWrapper/config.jelly, comparing the post-build-step blocks around lines 105 and 160. Confirm the matrix block uses postMatrixBuildSteps and verify that saving a matrix project through the Jelly UI no longer duplicates post-build steps.
