locale "selectedItemsLabel" is broken on MultiSelect

[petitkriket]

Describe the bug

Hello,

Description of the issue

The mapping between MultiSelect selectedItemsLabel text and the global locale registration app configuration is broken
(selectionMessage)

minor: locale documentation page lack of a proper and fonctionnal example (would love to create one for you), as it could help to have a working stackblitz/codesandbox example with primevue (like for the components documentation)

Here is a basic reproduction

Context:

• it does not work by using global locale registration in main.ts for this specific message
• it works for every other messages of the same components
• it works by using the component prop directly (local override)
• the computed responsible for this shows no issue component code

Additionnal

Here is the issue related to primefaces/primelocale that I closed because it seem to be primevue related only

Reproducer

https://stackblitz.com/edit/ejwndf?file=src%2FApp.vue,src%2Fmain.js%3AL120-L120

PrimeVue version

3.35.0

Vue version

3.x

Language

TypeScript

Build / Runtime

Vite

Browser(s)

No response

Steps to reproduce the behavior

register a community locale (or any self writted one)
see how it is actually ignored by the component that should consume it (here a MultiSelect)

Expected behavior

global app wide locale registration should work when defined into main.ts
