Update of golang-github-gdamore-cell to 2.*

[Daniel Milde]

Hello Go Team,
I am starting with packaging Go stuff and would like to update 
golang-github-gdamore-tcell to version 2.*

This version is referenced as github.com/gdamore/tcell/v2 in go.mod and 
it's not backwards compatible with version 1.* which is on Salsa - 
https://salsa.debian.org/dundee/golang-github-gdamore-tcell

My question is: Should I update the current package or start a new one 
for it (golang-github-gdamore-tcell-v2)?

Thanks

Cheers
Daniel
