nginx: [warn] the "http2_push_preload" directive is obsolete & the "listen ... http2" directive is deprecated

[drbyte]

Description

Using nginx 1.25.2 (currently the latest version) and calling sudo nginx -t to test the config, reveals deprection/obsolete warnings in configs built from Valet's secure.valet.conf stub file:

nginx: [warn] the "listen ... http2" directive is deprecated, use the "http2" directive instead in ~/.config/valet/Nginx/foo.test:9
nginx: [warn] the "http2_push_preload" directive is obsolete, ignored in ~/.config/valet/Nginx/foo.test:15
nginx: the configuration file /opt/homebrew/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /opt/homebrew/etc/nginx/nginx.conf test is successful

partial quote of cli/stubs/secure.valet.conf, starting on line 8:
(Lines 9, 10, 15 affected)

server {
    listen 127.0.0.1:443 ssl http2;
    #listen VALET_LOOPBACK:443 ssl http2; # valet loopback
    server_name VALET_SITE www.VALET_SITE *.VALET_SITE;
    root /;
    charset utf-8;
    client_max_body_size 512M;
    http2_push_preload on;

Steps To Reproduce

Can also be seen in the output of sudo nginx -t when calling valet diagnose

Upgrade note:
NOTE whenever we change the secure.valet.conf stub file, then when you upgrade your Valet version, it will take effect automatically on each new domain you run valet secure on. You can optionally re-secure all your domains by running valet tld test (where test equates to your .test tld in use; substitute accordingly if you're not using Valet's only officially supported TLD of .test)

Diagnosis

Had the same problem with reinstalling latest valet and so also latest nginx.
