Increase timeout in TestParallel testing to reduce flaky failures (#12822)

Browse Source 
Currently, the following tests are flaky and failing intermittently, so I'm going to increase the timeout to improve stability.

```  
    1) Failure:
  TestParallel::TestParallel#test_hungup [/Users/runner/work/ruby/ruby/src/tool/lib/zombie_hunter.rb:6]:
  Expected [[42009, #<Process::Status: pid 42009 SIGKILL (signal 9)>]] to be empty.
  
    2) Error:
  TestParallel::TestParallel#test_hungup:
  Test::Unit::ProxyError: execution expired
      /Users/runner/work/ruby/ruby/src/lib/timeout.rb:40:in 'Timeout::Error.handle_timeout'
      /Users/runner/work/ruby/ruby/src/lib/timeout.rb:194:in 'Timeout.timeout'
      /Users/runner/work/ruby/ruby/src/tool/test/testunit/test_parallel.rb:210:in 'TestParallel::TestParallel#test_hungup'

```
