[BUG][angular typescript] latest docker image not reading configuration file

Description

we are using the latest docker image in our code generation for typescript angular. As we updated yesterday, the generator now errors out whenever we pass in a configuration file:

docker pull openapitools/openapi-generator-cli:latest

docker run --rm -v ${PWD}:/local -v $(pwd)/codegen_scripts/:/tmp/cfg openapitools/openapi-generator-cli:latest generate \
    -i http://ourpath-to-openapi.json \
    -g typescript-angular \
    **-c /tmp/cfg/config.json \** 
    -o /local/typescript-angular

where we have in codegen_scripts/config.json

{
  "additionalProperties": {
    "useHttpClient": true,
    "useNgPackagr": true,
    "basePath": "",
    "enumPropertyNaming": "UPPERCASE",
    "stringEnums": true
  },
  "ngVersion": "13.1.1",
  "npmName": "@activia/cm-api",
  "npmVersion": "52.4.5",
  "npmRepository": "https://ourepo/repository/npm-internal/",
  "supportsES6": true
}

openapi-generator version

openapitools/openapi-generator-cli@sha256:5cf9a2bd60dbd7a517ff462824fb8792168c074fe13e8dd4708718127f819939

Generation Details

Steps to reproduce

run the bash above against a valid openapi.json
-> expected: works and generates

-> actual:

Exception in thread "main" java.lang.NullPointerException
        at java.base/java.lang.String.concat(Unknown Source)
        at org.openapitools.codegen.CodegenConfigLoader.forName(CodegenConfigLoader.java:48)
        at org.openapitools.codegen.config.CodegenConfigurator.fromFile(CodegenConfigurator.java:94)
        at org.openapitools.codegen.cmd.Generate.execute(Generate.java:272)
        at org.openapitools.codegen.cmd.OpenApiGeneratorCommand.run(OpenApiGeneratorCommand.java:32)
        at org.openapitools.codegen.OpenAPIGenerator.main(OpenAPIGenerator.java:66)

removing the -c option works but generated httpclient.delete calls contain an extra parameter, we lost package.json info. As well using the latest-release image has the same extra parameter in the delete as well and thus the generated code won't compile.

https://github.com/OpenAPITools/openapi-generator/issues/11276

Reproduce the Docker command with the provided config.json and inspect CodegenConfigLoader.java, especially forName, followed by CodegenConfigurator.fromFile and Generate.execute in the stack trace. Compare behavior with and without -c and review issue 11276. Done means the configuration file loads successfully and typescript-angular output retains the package metadata without the extra delete parameter.
