The repo in CentOS 8+ is error

[tiyee]

If your OS version is CentOS 8+, you should use the new repo in the link: https://openresty.org/package/pubkey2.gpg , not in https://openresty.org/package/pubkey.gpg.

If you use the second one, you'll receive the error like this

The GPG keys listed for the "Official OpenResty Open Source Repository for CentOS" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.. Failing package is: openresty-1.21.4.2-1.el9.x86_64
 GPG Keys are configured as: https://openresty.org/package/pubkey.gpg

Wish to fix this bug in website.
