'downloads' CDN mirrors out of sync

[Eric]

While investigating https://forum.openwrt.org/t/the-openwrt-firmware-selector/81721/818, I stumbled across this:

$ curl -s https://downloads.openwrt.org/snapshots/targets/mediatek/mt7622/profiles.json | jsonfilter -e '$.version_code'
r26912-3c95641366

$ curl -s https://mirror-03.infra.openwrt.org/snapshots/targets/mediatek/mt7622/profiles.json | jsonfilter -e '$.version_code'
r26928-238aa35c49

The ASU server's version is the same as mirror-03, so it's updating ok, but the generic 'downloads' from near Los Angeles is out of date...

$ curl -s https://sysupgrade.openwrt.org/json/v1/snapshots/targets/mediatek/mt7622/linksys_e8450-ubi.json | jsonfilter -e '$.version_code'
r26928-238aa35c49
