Safe to ignore these errors when installing mail-receiver?

Hi, Thank you for your work to make direct-delivery so much easier!

When building the container, I get one error message that it can’t find ruby and one warning on locales
Full output:

/var/discourse$ sudo ./launcher bootstrap mail-receiver
x86_64 arch detected.

/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Is this safe to ignore or a bug?
Using latest commit 8c40388ae4dabf1c0052ddd8eab4c72dbf7e0ca3 on branch main.

I suspect it’s OK. Start it up and see if it works.
