BUG: Inconsistent library name in Header files

Following FO should have libfieldFunctionObjects.so in respective documentation header files.

• DESModelRegions/DESModelRegions.H
• PecletNo/PecletNo.H
• Q/Q.H
• vorticity/vorticity.H
• yPlus/yPlus.H

Similarly perhaps following also need update

• src/functionObjects/lagrangian/cloudInfo/postProcessingDict
