ext/ripper/lib/ripper/lexer.rb: Do not deprecate Ripper::Lexer::State#[]

Browse source 
The old code of IRB still uses this method. The warning is noisy on
rails console.
In principle, Ruby 3.1 deprecates nothing, so let's avoid the
deprecation for the while.
I think It is not so hard to continue to maintain it as it is a trivial
shim.
