Describe the bug

When running the generator and using podman with a large uid (over 100000), launching the OCI container fails with an error.

[[v1] src/openapi/api-docs.json] Error: OCI runtime error: crun: setresuid to xxxxxxxxxx: Invalid argument

openapi-generator-cli is running the OCI container with command line option --user xxxxxxxxxx:yyyyy and this is outside the range of available namespace users.

Steps to reproduce the behavior:

1. Log in with a user with uid > 100000.
2. Configure openapitools.json with "useDocker": true
3. Run npx openapi-generator-cli generate
4. See error

Expected behavior

Generator runs and generates files

Additional Comments

I am using rootless podman with the docker command mapped to podman behind the scenes.

Also, I did find this: containers/podman#21293

It indicates that an additional parameter might be needed: --userns=keep-id:uid=xxxxxxxxxx,gid=yyyyy

Updated to include that I am using rootless podman.

I added 10000 < a.uid ? `--userns-keep-id:uid${a.uid}=,gid=${a.gid}` : "" , to the docker command line in main.js, and that worked.
