Fix Ruby 3.1 deprecation warning with ERB.new

stanhu commented 1 year ago

This eliminates the warning:

warning: Passing trim_mode with the 3rd argument of ERB.new is deprecated. Use keyword argument like ERB.new(str, trim_mode: ...) instead.

Per https://bugs.ruby-lang.org/issues/14256, trim_mode needs to be a keyword argument. This is compatible with Ruby 2.7 and on.
