[REG 1.1.0 -> 1.1.1] Docs installation path has minor difference

Certification, Design and Verification documents are installed in different path compared to 1.1.0.

1.1.0:

Docs/QtSafeRenderer-1.1.0/QSR 1.1/Certification_documentation

1.1.1:

Docs/QtSafeRenderer-1.1.1/Certification_documentation

NOTE, when installing QSR1.1.1 to macOS the docs are installed in 1.1.0 style, linux and win use 1.1.1 style. Should be unified in all platforms.
