GNUInstallDirs: Update FreeBSD texinfo destination to share/info
FreeBSD ports commit r484628 explains that FreeBSD decided to install texinfo files (GNU info) into ${PREFIX}/share/info
. Update CMake's default accordingly.
We already made a similar change for GNU/kFreeBSD in !2511 (merged).
Fixes: #18585 (closed)
Topic-rename: GNUInstallDirs-FreeBSD-info
