www/nginx-devel: update from 1.23.2 to 1.23.3

Update HTTPv3/QUIC patch.

<Changelog>

*) Bugfix: an error might occur when reading PROXY protocol version 2

header with large number of TLVs.

*) Bugfix: a segmentation fault might occur in a worker process if SSI

was used to process subrequests created by other modules.
Thanks to Ciel Zhao.

*) Workaround: when a hostname used in the "listen" directive resolves

to multiple addresses, nginx now ignores duplicates within these
addresses.

*) Bugfix: nginx might hog CPU during unbuffered proxying if SSL

connections to backends were used.
