Feature: Add pre-compiled release binaries for Linux ARM64 (aarch64)

[Cyrah2R]

Describe your idea

Hi team!

Currently, the release assets only include binaries for x86_64 architectures. With the rise of ARM-based cloud instances (like AWS Graviton and Oracle Cloud ARM), having native aarch64 binaries would be incredibly helpful for deployments.

I have successfully compiled and tested the binary for aarch64-unknown-linux-gnu.

I would like to submit a Pull Request to update the GitHub Actions release workflow to automatically build and include this target in future releases. Let me know if you are open to this!

Hi @Cyrah2R, looks like we already provide library binaries for c2pa-rs (see https://github.com/contentauth/c2pa-rs/releases/tag/c2pa-v0.79.3 as an example), but do not publish c2patool binaries for aarch64-unknown-linux-gnu. We would welcome the PR as you've suggested. Please also update the file https://github.com/contentauth/c2pa-rs/blob/main/docs/support-tiers.md as part of your PR.

Thanks @scouten-adobe! I completely agree.
I've just updated the linked PR (#1998) to include the aarch64-unknown-linux-gnu target in docs/support-tiers.md, and I also fixed a minor typo in the existing Ubuntu (ARM) targets there.
Let me know if everything looks good on the PR side!
