Update ngx_mruby to 2.2.4 and nginx to 1.21.3

[edmorley]

The binary build process for this buildpack uses the default nginx version specified by ngx_mruby. As such, updating ngx_mruby from 2.2.3 to 2.2.4 means the bundled nginx version is also updated from 1.19.0 to 1.21.3: https://github.com/matsumotory/ngx_mruby/blob/v2.2.3/nginx_version https://github.com/matsumotory/ngx_mruby/blob/v2.2.4/nginx_version

Changes: https://github.com/matsumotory/ngx_mruby/releases/tag/v2.2.4 https://nginx.org/en/CHANGES

Confirmed still working on Heroku-20

Did we check on heroku-18?

[edmorley]

Did we check on heroku-18?

No, because the main issue is "are the ngx_ruby templates in this repo still compatible with newer ngx_mruby" (albeit compat issues are unlikely given only a bump from 2.2.4 to 2.2.5), and the files are the same across all stack versions.

[edmorley]

I checked Heroku-18 now just in case, and it was fine.
