Use Timeout.timeout instead of Object#timeout

[mishina2228]

Fix #263.

This change suppresses the following warning on Ruby 2.7:

warning: Object#timeout is deprecated, use Timeout.timeout instead.

[mishina2228]

Object#timeout is removed from Ruby 3.0 3.1, so god cannot be used with Ruby 3.0+ 3.1+.

$ irb
irb(main):001:0> RUBY_VERSION
=> "2.7.0"
irb(main):002:0> timeout(1) {}
(irb):2: warning: Object#timeout is deprecated, use Timeout.timeout instead.
=> nil

$ irb
irb(main):001:0> RUBY_VERSION
=> "3.1.2"
irb(main):002:0> timeout(1) {}
(irb):2:in `<main>': undefined method `timeout' for main:Object (NoMethodError)
        from /home/owner/.rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/gems/irb-1.4.1/exe/irb:11:in `<top (required)>'
        from /home/owner/.rbenv/versions/3.1.2/bin/irb:25:in `load'

Object#timeout is still available in ruby 3.0.2,
However, with timeout 0.2.0+, Object#timeout is removed.

$ gem list timeout

@mishina2228

Object#timeout is deprecated but still available in ruby 3.0.2
https://github.com/ruby/ruby/blob/v3_0_2/lib/timeout.rb#L124-L134

% docker run --rm -ti ruby:3.0.2 
irb(main):001:0> RUBY_VERSION
=> "3.0.2"
irb(main):002:0> timeout(1) {}
(irb):2: warning: Object#timeout is deprecated, use Timeout.timeout instead.
=> nil
irb(main):003:0> 

But if timeout gem is updated to 0.2.0 or later
by gem install timeout or bundler, Object#timeout is removed.

@mishina2228 Did you update timeout gem?

Anyway, to run god with ruby 3.1+, this PR is necessary.

[mishina2228]

@minimum2scp Ah, you're right! I was using timeout v0.2.0.

$ ruby -v
ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-linux]
$ gem list timeout

*** LOCAL GEMS ***

timeout (0.2.0, default: 0.1.1)

Thanks for pointing out and explaining in detail!
I will edit comments... Done.
