TableBuilderHelper::Column#link_to: Allow arbitrary number of arguments

This enables us to pass multiple objects into the lambda, so that we can
for example build a URL using a Rails helper using multiple objects.

Example:

    column.link_to(referential, item)

    lambda do |referential, item|
      some_path(referential, item)
    end
