Add compile task in Development section

[genya0407]

When I followed the instructions in the Development section, I found some tests failing with Ruby 3.3.1 and older Rubies:

(See full trace by running task with --trace)

It turned out that this was because I had not executed the rake compile before running rake test.
We should have compile task in the Development section so that new contributors don't stumble.

FYI: CI runs rake compile test.

zlib/.github/workflows/test.yml

Line 42 in 950dad7

run: bundle exec rake compile test
