Allow use of private `configs`

[eviln1]

I would like to be able to use commitlint configs from private packages or repositories.

I believe this is not currently possible for the following reasons:

• Passing NPM_TOKEN environment variable through contexts or project configuration is not sufficient, because without the -E switch, sudo drops environment variables.
• Even if -E switch was used, any .npmrc config present in the project would not be read.
• The orb doesn't allow overriding the executor or the docker image, so I cannot use an image which running as root such as node:18.14
• AFAICT npm doesn't allow passing _authToken on the CLI, meaning I cannot piggy-back the configs parameter to inject CLI options.
• I can't attach a workspace with node_modules where I would have previously installed the private package.
• I can't write a custom job re-using a command from the orb, because there are none.

I will gladly open a PR to address this, but I'd like to know what would be your favorite method of solving this.

Regards,
