Fix issue with the inputs including || in the value

[AdamJHall]

Description of the proposed changes
Input values are including the || in them as it is not evaluated at runtime. I've moved it into the templating functions so it actually gets evaluated and not printed.

Example:

Invalid bucket name "pwa-staging.ovarohome.com.au || ": Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$" or be an ARN matching the regex "^arn:(aws).*:(s3|s3-object-lambda):[a-z\-0-9]*:[0-9]{12}:accesspoint[/:][a-zA-Z0-9\-.]{1,63}$|^arn:(aws).*:s3-outposts:[a-z\-0-9]+:[0-9]{12}:outpost[/:][a-zA-Z0-9\-]{1,63}[/:]accesspoint[/:][a-zA-Z0-9\-]{1,63}$"

According to the docs, this syntax looks correct now. LGTM.
