Failed to compile under MacOS 10.12

[lalawue]

for bee.lua only support c++17, and with ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED >= 101500.

but actually OS version limitation is not neccessary.

so I modified a version working under MacOS 10.12, https://github.com/lalawue/lua-language-server/releases/tag/v20200137.

bee.lua just limits macos to 10.13 or later. I have no intention of probing its lowest supported version because I cannot guarantee sufficient testing and quality.
Maybe one day I will increase the minimum version to 10.15, because this is the first version to support c ++ 17 features. It can reduce a lot of unnecessary code.

Ok, thank you all the same.
