bump premailer version

[rex-remind101]

This gem relies on a very old version of premailer, namely one that includes hpricot whose hpricot_slate_method_added magic causes issues with sorbet. Please update this dependency to use a more recent version of premailer.

This is the dependency definition:

premailer-rails/premailer-rails.gemspec

Line 24 in 43ef66e

s.add_dependency 'premailer', '~> 1.7', '>= 1.7.9'

premailer is currently at 1.11.1. If you do a fresh install of premailer-rails, it will install the latest premailer version. Thus, you should be able to simply run bundle update premailer to get a newer version of premailer in your project.
