Use updated Html2Text library via composer
What does this MR do?
Html2Text library is used when fetching emails into the internal mail system, because they should be shown as text only.
This MR imports the library via composer instead of having it inside the lib folder
How confident are you it won't break things if deployed?
Needs manual testing as the process of receiving mails is far away from being tested. I did not manually execute the code and no test does either. It can be checked after beta deployment by using this manually once inbetween the CRON runs of the production one.
