docs: Sets whether the parser should trim quotes from command line arguments before processing them. The default is
  read from the system property "picocli.trimQuotes" and will be {@code true} if the property is set and empty, or
  if its value is "true".
  <p>The specified setting will be registered with this {@code CommandLine} and the full hierarchy of its
  subcommands and nested sub-subcommands <em>at the moment this method is called</em>. Subcommands added
  later will have the default setting. To ensure a setting is applied to all
  subcommands, call the setter last, after adding subcommands.</p>
  <p>Calling this method will cause the "picocli.trimQuotes" property to have no effect.</p>
  @param newValue the new setting
  @return this {@code CommandLine} object, to allow method chaining
