[https://sysupgrade.openwrt.org/] Add mention of `apk` under 'How do use this server'

[Bruxism]

How to use this server: There are at least three clients that can request a new image from the Sysupgrade Server:

    [LuCI Package:](https://github.com/openwrt/asu#luci-app) opkg install luci-app-attendedsysupgrade
    [Command line/SSH (OpenWrt >23.xx) :](https://github.com/openwrt/asu#cli) opkg install owut
    [Command line/SSH:](https://github.com/openwrt/asu#cli) opkg install auc

I thought someone would appreciate notice to add info about using apk instead of opkg now for the latest editions of OpenWRT.

Good idea! Could you kindly create a PR?

Thanks for the quick reply.

Forgive my ignorance, but I don't recognize how to that for this issue. I understood that to do a pull request, I'd have to suggest changing something about a repo, but I don't believe that the website itself https://sysupgrade.openwrt.org/ is in the repo--nor do I recognize a repo for the website itself.

the website itself

I think what you are looking for is the static front page template:
