Update ruby-puma package to 5.0.0.
## 5.0.0
* Features
* Allow compiling without OpenSSL and dynamically load files needed for SSL, add 'no ssl' CI (#2305)
* EXPERIMENTAL: Add `fork_worker` option and `refork` command for reduced memory usage by forking from a worker process instead of the master process. (#2099)
* EXPERIMENTAL: Added `wait_for_less_busy_worker` config. This may reduce latency on MRI through inserting a small delay before re-listening on the socket if worker is busy (#2079).
* EXPERIMENTAL: Added `nakayoshi_fork` option. Reduce memory usage in preloaded cluster-mode apps by GCing before fork and compacting, where available. (#2093, #2256)
* Added pumactl `thread-backtraces` command to print thread backtraces (#2054)
* Added incrementing `requests_count` to `Puma.stats`. (#2106)
* Increased maximum URI path length from 2048 to 8192 bytes (#2167, #2344)
* `lowlevel_error_handler` is now called during a forced threadpool shutdown, and if a callable with 3 arguments is set, we now also pass the status code (#2203)
* Faster phased restart and worker timeout (#2220)
* Added `state_permission` to config DSL to set state file permissions (#2238)
* Added `Puma.stats_hash`, which returns a stats in Hash instead of a JSON string (#2086, #2253)
* `rack.multithread` and `rack.multiprocess` now dynamically resolved by `max_thread` and `workers` respectively (#2288)
* Deprecations, Removals and Breaking API Changes
* `--control` has been removed. Use `--control-url` (#1487)
* `worker_directory` has been removed. Use `directory`.
* min_threads now set by environment variables PUMA_MIN_THREADS and MIN_THREADS. (#2143)
* max_threads now set by environment variables PUMA_MAX_THREADS and MAX_THREADS. (#2143)
* max_threads default to 5 in MRI or 16 for all other interpreters. (#2143)
* preload by default if workers > 1 (#2143)
* Puma::Plugin.workers_supported? has been removed. Use Puma.forkable? instead. (#2143)
* `tcp_mode` has been removed without replacement. (#2169)
* Daemonization has been removed without replacement. (#2170)
* Changed #connected_port to #connected_ports (#2076)
* Configuration: `environment` is read from `RAILS_ENV`, if `RACK_ENV` can't be found (#2022)
* Log binding on http:// for TCP bindings to make it clickable
* Bugfixes

* Improve shutdown reliability (#2312, #2338)
* Close client http connections made to an ssl server with TLSv1.3 (#2116)
* Do not set user_config to quiet by default to allow for file config (#2074)
* Always close SSL connection in Puma::ControlCLI (#2211)
* Windows update extconf.rb for use with ssp and varied Ruby/MSYS2 combinations (#2069)
* Ensure control server Unix socket is closed on shutdown (#2112)
* Preserve `BUNDLE_GEMFILE` env var when using `prune_bundler` (#1893)
* Send 408 request timeout even when queue requests is disabled (#2119)
* Rescue IO::WaitReadable instead of EAGAIN for blocking read (#2121)
* Ensure `BUNDLE_GEMFILE` is unspecified in workers if unspecified in master when using `prune_bundler` (#2154)
* Rescue and log exceptions in hooks defined by users (on_worker_boot, after_worker_fork etc) (#1551)
* Read directly from the socket in #read_and_drop to avoid raising further SSL errors (#2198)
* Set `Connection: closed` header when queue requests is disabled (#2216)
* Pass queued requests to thread pool on server shutdown (#2122)
* Fixed a few minor concurrency bugs in ThreadPool that may have affected non-GVL Rubies (#2220)
* Fix `out_of_band` hook never executed if the number of worker threads is > 1 (#2177)
* Fix ThreadPool#shutdown timeout accuracy (#2221)
* Fix `UserFileDefaultOptions#fetch` to properly use `default` (#2233)
