Fix zls downloads

[pfgithub]

anyzls for zig 0.15.0 didn't work (download url was wrong), now it does. It uses the api described here https://github.com/zigtools/release-worker/blob/master/README.md (#17 (comment))

Unfortunately, it still doesn't work with the official Zig extension for vscode because vscode determines the zls version by running zls --version but without setting a cwd, so it runs it in C:\Users\pfg\AppData\Local\Programs\Microsoft VS Code. The issue is here: https://github.com/ziglang/vscode-zig/blob/1e34279fccc2b29272ec2bf44a1242427ac5316d/src/zigUtil.ts#L213 . Either the vscode-zig extension would need to be updated to run in the workspace directory, or anyzig would need a way to set the default version to use when no build.zig is present.

Hi @pfgithub,

I tried your fork yesterday. I can confirm, it works really well: zls version is selected properly based on zig version.

I made getanyzig – a convenient installer, that uses the current master (or in this case your branch pfg/fix-zls). No zig installation required prior to installing it. Hope this helps someone.
