Argument --type-list requires other arguments

[dshahbaz]

Expected --type-list to just list the types:

❯ ruplacer  --version
ruplacer 0.8.0
❯ ruplacer  --type-list
error: The following required arguments were not provided:
    <PATTERN>
    <REPLACEMENT>

USAGE:
    ruplacer --type-list <PATTERN> <REPLACEMENT>

For more information try --help

Workaround was to just spam some arguments:

❯ ruplacer  --type-list a b
