mn create-acme-account help output misleading about existing keys

[msgilligan]

The documentation for mn create-acme-account says "This command will either create a new account keypair for you or you can pass the account keypair that you have generated using the mn create-key or via openssl or other means in as a parameter." (And the command does seem to behave according to the documentation.)

However the command help implies a key is always created.

Steps to Reproduce

1. mn create-acme-account --help

Expected Behaviour

• Help output should indicate an existing key can be used

Actual Behaviour

Usage: mn create-acme-account [-fhvVx] -e=<email> [-k=<keyDir>] -n=<keyName> [-s=<keySize>]
                              (-u=<serverUrl> | --lets-encrypt-prod | --lets-encrypt-staging)
Creates a new account on the given ACME server
  -e, --email=<email>        Email address to create account with.
  -f, --force                Whether to overwrite existing files
  -h, --help                 Show this help message and exit.
  -k, --key-dir=<keyDir>     Custom location on disk to put the key to be used with this
                               account.
                               Default: src/main/resources
  -n, --key-name=<keyName>   Name of the key to be created
  -s, --key-size=<keySize>   Size of the key to be generated
                               Default: 4096
  -v, --verbose              Create verbose output.
  -V, --version              Print version information and exit.
  -x, --stacktrace           Show full stack trace when exceptions occur.
ACME server URL
      --lets-encrypt-prod    Use the Let's Encrypt prod URL.
      --lets-encrypt-staging Use the Let's Encrypt staging URL
  -u, --url=<serverUrl>      URL of ACME server to use

Weird, I just ran mn create-acme-account another time (this time with --lets-encrypt-prod option) and got the following output:

Key already exists and can be found here : ~/xxx/account-key.pem. If you want to overwrite it use the -f/--force flag.
Account creation complete. Make sure to store your account pem somewhere safe as it is your only way to access your account.

OK, the create key output was correct -- the problem was I was using ~ in the directory path and it wasn't being substituted.

However, the --help output is still misleading.

NOTE: Issue title and first comment have been updated to reflect that the problem is only with --help output.

Since the actual code is in the micronaut-starter project, I opened an issue over there:
