[Ruby] Memory passed to Arrow::Buffer.new is freed by GC while an array still refers to it #54688

Describe the bug, including details regarding any error messages, version, and platform.

An array built on an Arrow::Buffer created from a String reads freed memory once the Buffer object is garbage collected, although the array is still referenced.

require "arrow"

chunked = Arrow::ChunkedArray.new([Arrow::Int32Array.new(3, Arrow::Buffer.new([1, 2, 3].pack("l*")), nil, 0)])
GC.start
Array.new(10000) { [7, 7, 7].pack("l*") }
p chunked.to_a
# => [10860, 0, 0]

Environment: red-arrow 25.0.1, apache-arrow-glib 25.0.1 (Homebrew), Ruby 3.4.1, macOS 15.4.1 (arm64)
