Spelling of macOS in long_os_version

[dtolnay]

On laptop, desktop, and server computers produced by Apple Inc., System::long_os_version() returns strings that are not historically accurate based on https://en.wikipedia.org/wiki/MacOS_version_history. The naming used by Apple for these operating systems was "Mac OS X", then "OS X", then "macOS".

"MacOS 10.0 Cheetah"	Mac OS X
"MacOS 10.1 Puma"
"MacOS 10.2 Jaguar"
"MacOS 10.3 Panther"
"MacOS 10.4 Tiger"
"MacOS 10.5 Leopard"
"MacOS 10.6 Snow Leopard"
"MacOS 10.7 Lion"
"MacOS 10.8 Mountain Lion"	OS X
"MacOS 10.9 Mavericks"
"MacOS 10.10 Yosemite"
"MacOS 10.11 El Capitan"
"MacOS 10.12 Sierra"	macOS
"MacOS 10.13 High Sierra"
"MacOS 10.14 Mojave"
"MacOS 10.15 Catalina"
"MacOS 11.0 Big Sur"
"MacOS 12.0 Monterey"
"MacOS 13.0 Ventura"
"MacOS 14.0 Sonoma"
"MacOS 15.0 Sequoia"

I would expect sysinfo to render these names in a way that is consistent with Apple's name for each of these operating systems: "macOS 15.0 Sequoia", "OS X 10.11 El Capitan", "Mac OS X 10.7 Lion"

Makes sense. Currently in the middle of moving to a new place so I'll take a look at it likely next week if no did until then.
