Describe the bug

How to generate code for specific endpoint? specifying --globalProperty=apis=user is not working.

Steps to Reproduce

1. Create openapitools.json with globalProperty such that it generates code only for user endpoints

{
  "$schema": "./node_modules/@openapitools/openapi-generator-cli/config.schema.json",
  "spaces": 2,

  "generator-cli": {
    "version": "6.6.0",
    "generators": {
      "petstore": {
        "generatorName": "typescript-nestjs",
        "inputSpec": "https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml",
        "output": "src/petstore/codegen",
        "skipValidateSpec": true,
        "globalProperty": {. <---<<<
          "apis": "user"
        },
        "additionalProperties": {
          "modelPropertyNaming": "camelCase",
          "useSingleRequestParameter": true
        }
      }
    }
  }
}

2. Generate code

 openapi-generator-cli generate --generator-key petstore

output: (you can see the --global-property="apis=user" is created. )

 java -jar "..../.nvm/versions/node/v16.17.0/lib/node_modules/@openapitools/openapi-generator-cli/versions/6.6.0.jar" generate --input-spec="https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml" --generator-name="typescript-nestjs" --output="src/petstore/codegen" --skip-validate-spec --global-property="apis=user" --additional-properties="modelPropertyNaming=camelCase,useSingleRequestParameter=true" exited with code 

3. no code is generated and no errors

Expected behavior

Update documentation on how to generate code for specific endpoints. Current globalProperties -> apis
