Upgrade script sometimes failed

1. What version of V2Ray are you using (If you deploy different version on server and client, please explicitly point out)?
   v4.22.1

2. What's your scenario of using V2Ray? E.g., Watching YouTube videos in Chrome via Socks/VMess proxy.
   General day-to-day use

3. What did you see? (Please describe in detail, such as timeout, fake TLS certificate etc)
   The upgrade script failed sometimes. I have pinpoint the issue to this command to obtain the new version. (

   v2ray-core/release/install-release.sh

   Line 258 in 2227557

   NEW_VER="$(normalizeVersion "$(curl ${PROXY} -s "${TAG_URL}" --connect-timeout 10| grep 'tag_name' | cut -d\" -f4)")"

   )

curl -s "https://api.github.com/repos/v2ray/v2ray-core/releases/latest" --connect-timeout 10| grep 'tag_name' | cut -d\" -f4

Sometimes it prints out the correct version, i.e. v4.23.1. But sometimes it prints out this https://api.github.com/repos/v2ray/v2ray-core/releases/24822244, which leads to the download failure.

4. What's your expectation?
   It always gets the correct latest version.
