Fix io.meeds.distribution property version affectation (#2269)

Before this fix, when checking /rest/platform/info, the
`io.meeds.distribution` property is missing which raises an exception.
This change will ensure that the missing property gets the correct
platform version

```bash
org.exoplatform.commons.info.MissingProductInformationException: Missing product information property: io.meeds.distribution
	at org.exoplatform.commons.info.ProductInformations.getVersion(ProductInformations.java:163)
