Change "enable replacement" error text to "allow replacement" to match command-line interface

[ianloic]

I'm a very happy rpm-ostree user on Fedora Silverblue, but sometimes when I want to make a live change to my system with:

rpm-ostree install -A blah

I'll get an error message like:

error: packages would be changed: 34, enable replacement to override

and then I think oh, I have to pass that override so I do

sudo rpm-ostree apply-live --enable-replacement

but the argument is not --enable-replacement, it is in fact --allow-replacement.

This PR changes that error text to more closely match the correct command-line argument needed to override the error, so the error would now be:

error: packages would be changed: 34, allow replacement to override

It's subtle, but I think an ever so slight usability improvement.

Hi @ianloic. Thanks for your PR.

I'm waiting for a coreos member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
