Add some additional architectures

[agriyakhetarpal]

Based on https://launchpad.net/~gohugoio/+snap/hugo-dev, two additional architectures: PowerPC (ppc64le and armhf (most likely armv7l) can be added.

• 🔋 Build wheels for PowerPC64 little-endian (ppc64le) #92
• Not sure for armhf, it's blocked on manylinux due to the absence of CI runners (ARM builds? pypa/manylinux#1405, feature: add musllinux_1_2_armv7l pypa/manylinux#1455), and subsequently cibuildwheel (arm32 / armv7l wheels pypa/cibuildwheel#1421), or they need to be built with Zig (Cross-compile builds pypa/manylinux#1125), and those are some which I won't be publishing to PyPI at this time, even though the powerpc64le-linux-gnu target triplet is working).

https://go.dev/wiki/GoArm#supported-architectures says that GOARM will be picked up for native compilation if done on the piwheels index end. Otherwise, it should be wise to add GOARM="7" to the command when using Zig. Outputs were identical with the above one from file.

Cross-compilation not enabled yet (and not yet for s390x or ppc64le either)
