Disable file-system watching on macOS 11 and before

[lptr]

File-system watching only works well on macOS 12+. This updates the documentation and automatically disables it on macOS 11 and earlier.

New native code that breaks on macOS 11 and earlier was introduced in 8.8 in:

• Use new macOS file-system event delivery in file-system watching #28259

Note: We don't have macOS 11 or earlier in our CI fleet, so we can't actually test this automatically.

Fixes #29476

Thank you so much for this fix !
Ran into this on OS X 10.15 with Gradle 8.8 ( tried every conceivable java and workaround - like a brick wall )
Tested 8.9 RC 1 - works like a charm !
Thank you ! It's good to have current / next Gradle available, and not resort to reverting and working around !
( As old and deprecated as OS X 10.15 is - there are those of us who still have to use it, and it's very appreciated )
