Fix visibility decorator of Ogre2Projector

🦟 Bug fix

Fix visibility decorator of Ogre2Projector class.

Summary

Ogre2Projector was decorated by GZ_RENDERING_OGRE_VISIBLE instead of GZ_RENDERING_OGRE2_VISIBLE, probably a copy&paste error.

I noticed this as by building gz-rendering with SKIP_ogre, the build was failing with:

In file included from /home/traversaro/gz-ws/src/gz-rendering/ogre2/src/Ogre2Projector.cc:30:
/home/traversaro/gz-ws/src/gz-rendering/ogre2/include/gz/rendering/ogre2/Ogre2Projector.hh:26:10: fatal error: gz/rendering/ogre/Export.hh: No such file or directory
   26 | #include "gz/rendering/ogre/Export.hh"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
