Tldr: Rename: pages/{osx => macos}

[bl-ue]

With macOS Big Sur, the major version of macOS has changed from 10 to 11. Now the osx folder is wrong because it's macOS 11, not macOS X.

CLIENT-SPECIFICATION.md needs to be updated.

Theses page need to be updated too:

pages/common/spatial.md
pages/osx/bless.md
pages/osx/pkgutil.md
pages/osx/afinfo.md
pages.es/osx/afinfo.md
pages.zh/osx/afinfo.md

Hey there, @bl-ue! Thanks for bringing this up. Unfortunately, this is a difficult problem, as a platform rename will result in a breaking change for tldr clients. Updating all of the tldr clients out there is a big task that will take quite a long time. Furthermore, we'll need to figure out a way to do this in a non-breaking fashion, to avoid causing issues for clients during the transition period.

all of the tldr clients out there

@sbrl Are there more clients then the Node.js client, the Python client, and the C client?

[sbrl]

Absolutely! Check out the list here: https://github.com/tldr-pages/tldr/#how-do-i-use-it

tldr-pages has a large and diverse community :D

Wow, I can't believe I didn't notice that section. Hm...we could just merge this issue into #4120, @sbrl?

[sbrl]

Ah, no worries!

Yeah, probably. It's a large and complex operation that requires lots of co-ordination. Somehow I don't think it's going to happen anytime soon, I'm afraid.

[bl-ue]

I might be able to coordinate it some time :)
