Linux ARM64 binaries removed - possible ways to bring them back

I noticed that Linux ARM64 AppImage has been disabled in #8427, which seems to be related to missing multi-architecture support in the enterprise offering. As a daily user of Insomnia on Linux ARM64, and the author of #8306 and #8331, I understand there are practical reasons, but still feel really unfortunate.

I'd like to know if it's possible to restore building of the AppImage artifacts. If the output artifact name is the only problem (i.e. the existing ones should not be changed), and an extra artifact wouldn't break anything, I can put up a PR to update the actions to do just that. If there are other non-secret reasons, I'd also like to know.

Review issue #8427 and the repository’s GitHub Actions workflows that disabled Linux ARM64 AppImage output. Trace the existing artifact naming and multi-architecture constraints; done means establishing whether an additional artifact can be built without breaking enterprise support and documenting or implementing the viable path.
