Remove aarch64-unknown-linux-gnu release asset

[andreamah]

In microsoft/vscode-ripgrep@a85a687, we change vscode-ripgrep to only consume aarch64-unknown-linux-musl for arm64 linux and not the gnu version. If nobody is using it, we should remove it as a released asset.

@Siddhesh-Ghadi @ghatwala We saw that you use these prebuilts for https://github.com/eclipse-che/che-theia. Would removing our aarch64-unknown-linux-gnu be an issue for you all?

hi @andreamah https://github.com/microsoft/ripgrep-prebuilt/pull/2/files here we had added support for power , z only and we wont be impacted at least by removing above but there may be others who are consuming this which we aren't aware of.

I see, thanks for the quick response. Since this repo only really supports the vscode-ripgrep repo, others are responsible for any breakages that happen from changes to this repo.

I just wanted to reach out because I was told that Theia also uses it. 🙂
