arm64 binary not working on rpi4 (aarch64) raspbian bookworm

[khimaros]

Describe the bug
binary is not executable on this architecture

To Reproduce
i tried installing manually from releases (arm64) as well as with the install script

$ ./rtx/bin/rtx 
bash: rtx/bin/rtx: cannot execute: required file not found

Expected behavior
rtx invokes successfully

rtx doctor output

not applicable

Additional context

$ uname -a
Linux 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

$ lsb_release -a
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 12 (bookworm)
Release:        12
Codename:       bookworm

the issue seems to be 64bit kernel with 32bit user space. in other words, i would need an armhf build of rtx in order to use it on this installation.
