packaging consistency for github releases

[visheyra]

Hi there,

While automating the download and execution of pint across various devices (mainly apple m1 arm64 and x86_64 linux) I noticed a difference in packaging.

When one download the darwin arm64 release the tarball contains the arm64 arch both in the name of the archive and within the archive

link:https://github.com/cloudflare/pint/releases/download/v0.30.2/pint-0.30.2-darwin-arm64.tar.gz

❯ ls pint-0.30.2-darwin-arm64
LICENSE			README.md		pint-darwin-arm64

However, for the linux release, the arch in the binary name has been changed

link: https://github.com/cloudflare/pint/releases/download/v0.30.2/pint-0.30.2-linux-x86_64.tar.gz content:

❯ ls pint-0.30.2-linux-x86_64
LICENSE			README.md		pint-linux-amd64

While it is not a huge problem I see 2 reasons why this should be fixed:

• when working with uname the expected architecture output on linux 64 bits is x86_64 not amd64
• it's a pain to write cross platform scripts due to that

I would be happy to help you tackle / PR this issue LMK
