[Feature #19236]
When building a large hash, pre-allocating it with enough
capacity can save many re-hashes and significantly improve
performance.

[Feature #19236]
In Ruby 3.3, `Hash.new` shall print a deprecation warning if keyword arguments
are passed instead of treating them as an implicit positional Hash.
This will allow to safely introduce a `capacity` keyword argument in 3.4
