fix: Remove trailing newlines from yaml arrays (#73)

Trailing newlines is something that we will never need as an
information, so it can only cause issues with parsing yaml values.

I scratched my head for 10 minutes on why my variable has a trailing
newline when I use `readarray -t` everywhere. Then I remembered
get_yaml_array function.

This should not affect current working modules at all, but it would be
good to test before landing.
