Can we update `rust-cross/rust-musl-cross` to ` rust-cross/manylinux-cross`?

I was trying to get a wheel for Python 3.14 and musllinux for a package of mine and I noticed that the image used for building on musllinux is rust-cross/rust-musl-cross, while for standard Linux the image used is ghcr.io/rust-cross/manylinux2014-cross:ARCH

I was taking a look at the repo for that image and it seems like there's support for musllinux: https://github.com/rust-cross/manylinux-cross/tree/main/musllinux_1_2 and the images seem to use the musl-cross image as a base: https://github.com/rust-cross/manylinux-cross/blob/main/musllinux_1_2/aarch64/Dockerfile#L3

Is there a reason why we are using rust-cross/rust-musl-cross? If not, I'd be happy to contribute a PR to update the references
