Fixes #891.

Thank you!

Amazing! Thanks.

Hello and thank you both for this. Although these arm64 builds are now available, some automated tooling (e.g. nvim-lsp-installer) does not pick them up since there hasn't been a release. Could you please consider possibly making a release sooner so that a manual install is not needed?

In fact, this PR did not successfully build arm64, but it is still x64.
I plan to fully implement and release this version this week.

Apologies @sumneko, you're right — I thought I could just add to the build process. I've had a look at luamake etc, but with my limited understanding of the lua ecosystem, there's not enough info for me to make the changes required. Apologies for the half-baked PR.

Unfortunately, I haven't found an easy way to compile linux-arm64, and there are still some problems that cannot be solved in the current cross-compilation.
Or we can wait for this: actions/runner-images#2552

The arm64 zip seems to work as expected, thanks.
