Homebrew does not understand Alpine's `glibc` and `ruby` versions are already new.

Hello!

Regarding the issue https://github.com/Homebrew/brew/issues/8130, published by @naumannt, where we have the same problem (observe he used musl, but I used your glibc), here is my little Docker log:

#44 238.9 Warning: Running in non-interactive mode because `stdin` is not a TTY.
#44 239.0 musl libc (x86_64)
#44 239.0 Version 1.2.3
#44 239.0 Dynamic Program Loader
#44 239.0 Usage: /lib/ld-musl-x86_64.so.1 [options] [--] pathname
#44 239.0 Homebrew requires Ruby 2.6 which was not found on your system.
#44 239.0 Homebrew portable Ruby requires Glibc version 2.13 or newer,
#44 239.0 and your Glibc version is too old. See:
#44 239.0   https://docs.brew.sh/Homebrew-on-Linux#requirements
#44 239.0 Please install Ruby 2.6 and add its location to your PATH.

I checked that Ruby version is 3.1.0, that is already newer than 2.6. I also checked glibc version, the same version you updated on your repository.

I also manipulated with the following code, based on @prantlf's docker-alpine-glibc:

But unsuccessfully.

@jonchang closed the issue as he said there were not maintainers interested in analysing this issue as they do not use Alpine Linux.

You could run brew with strace to see what call failed before the complaint about too old Ruby and Glibc was printed.

@prantlf, I couldn't run brew, as Homebrew isn't installed. I was trying to install Homebrew and received that versions errors.

Sorry for the late reply. Would you please provide a minimal Dockerfile that demonstrates this problem. Without that I cannot investigate this error further for you.
