Validate manifest provided mapping namespace (#10612)

Browse source 
With plugins adopting paperweights mapping namespaces in their manifest
file in and after paper 1.20.5, incorrectly spelled namespaces
previously were simply implied as the spigot namespace.

This commit properly ensures plugin authors are using a known mapping
namespace in their manifest, avoiding down the line confusion on
incorrect remapping behaviour.

The commit also fixes two incorrect log parameters.
