save the max_datagram_frame_size transport parameter in the session ticket (#4013)

Browse source 
* Add MaxDatagramFrameSize parameter in session ticket

* fix gofumpt issues

* Update integrationtests/self/zero_rtt_test.go

Co-authored-by: Marten Seemann <martenseemann@gmail.com>

* fix: correct comparsion of max_datagram_frame_size

* test: use constant MaxDatagramFrameSize for session ticket test

* fix grammar
