--apikey argument not working with version 2.5.0

[brknkfr]

Describe the bug
I specify a custom settings file under settings-custominstance.json for my custom etherpad-lite instance and specify it with the argument --settings. Until version 2.5.0 this worked for a custom APIKEY for the custom instance with --apikey APIKEY-custominstance.txt. The etherpad-lite version 2.5.0 won't start up with this argument any more. (The same for the --sessionkey argument.)

To Reproduce
Steps to reproduce the behavior:

1. Start etherpad-lite with the --apikey argument and specify an APIKEY-custom_instance.txt file: pnpm run prod --settings settings-custom_instance.json --apikey APIKEY-custom_instance.txt
2. Etherpad-lite throws an error:

> ep_etherpad-lite@2.5.0 prod src
> cross-env NODE_ENV=production node --require tsx/cjs node/server.ts --settings settings-custom_instance.json --apikey APIKEY-custom_instance.txt

src/node/utils/Cli.ts:51
    exports.argv.apikey = arg;
                 ^

Expected behavior
The argument --apikey (and --sessionkey) should still work.
