warning missing firmware /lib/firmware/i915/ in 5.11 kernel

[TQ]

I get a bunch of warning when install live-boot. looks like the linux-firmware missing some of the intel video card driver. I see it happens many times in different versions. A lot of people meet this issue. And some people hack it by download it manually from some website. But I don't like the way. I hope I can get some official solution because this bug is not new. And I am working on a project to make a customized file system. So I need it support AS More Firmware AS Possible and should stable and security. So I need make sure there have an official solution for this.

the following is the missing file and the kernel I am using. Hope it is enough to identity the issue.
