Different architecture for 1.77.2 when using on a arm mac

[tomaszklak]

Hi,

When I try to use official images, it looks like all of them report aarch64 as the running architecture. Except for the 1.77.2 version:

$ docker run --rm -it rust:1.77 uname -m
aarch64
$ docker run --rm -it rust:1.77.1 uname -m
aarch64
$ docker run --rm -it rust:1.77.2 uname -m
armv7l
$ docker run --rm -it rust:1.78 uname -m
aarch64

I would expect that it would be the same for all versions.

I'm on a macOS 13.6.6 (22G630) on Apple M2 Pro with docker desktop 4.25.0 (126437).
