Work around for VSC Bug - Fix Path Mappings to lowercase the drive letter

When using path mappings on windows, ensure the drive letter is lower cased. I.e. when user uses the following setup, ${workspaceFolder} gets translated to a path with an upper case drive letter.

      "pathMappings": [
        {
          "localRoot": "${workspaceFolder}/modules/rfidreader/",
          "remoteRoot": "/app/"
        }
      ],

This is a work around for a VSC bug

Suggestion

• Check src\client\debugger\extension\hooks\childProcessAttachService.ts -> fixPathMappings(). Use similar logic to resolve localRoot

const systemVariables = new SystemVariables(config.workspaceFolder);
const localRoot = systemVariables.resolveAny(<localRootProvided>);

• Then take the localRoot of path mappings and convert drive letter to lower case (on windows)
