Incorrect warning "Path is not a directory"

[Richhoef]

Type: LanguageService

Describe the bug

• OS and Version: Microsoft Windows [Version 10.0.18363.752]
• VS Code Version: 1.44.1
• C/C++ Extension Version: 2.27.0
  When I want to use the env section in c_cpp_properties, I get yellow squiggles under the paths at the default_forcedInclude saying "Path is not a directory". Although this is true, it is also completely irrelevant. The forcedInclude is ment to be a file (at least, in my case it is).

Steps to reproduce

Here is my c_cpp_properties.json:

{
   "env": {
       "default_includePath": [
         "${workspaceFolder}/some_path",
         "${workspaceFolder}/some_other_path"
       ],
       "default_defines": [
           "some_defines",
           "some_other_defines"
       ],
       "default_defines2": [
           "some_more_defines",
           "some_more_other_defines"
       ],
       "default_forcedInclude": [
           "${workspaceFolder}/some_path/some_file.h",
           "${workspaceFolder}/some_path/some_file.c"
        ],
        "default_browsepath": [
           "${workspaceFolder}/some_more_path",
           "${workspaceFolder}/some_more_other_path"
         ]
   },
   "configurations": [
       {
           "name": "Debug",
           "includePath": [ "${default_includePath}" ],
           "defines": [
               "${default_defines}",
               "${default_defines2}",
               "_DEBUG"
           ],
           "intelliSenseMode": "msvc-x64",
           "cStandard": "c89",
           "forcedInclude": [ "${default_forcedInclude}" ],
           "browse": {
               "path": [ "${default_browsepath}" ],
               "limitSymbolsToIncludedHeaders": true
           }
       }
   ],
   "version": 4
}

Expected behavior

I did not expect it to show a warning and yellow squiggles.
