Format for taplo release assets has changed
As of the 0.8 release, the taplo lsp server can't be installed using :LspInstallServer anymore, because the release assets are no longer .tar.gz files, but just .gz files. The format of the file names have also changed and more platforms are supported.
The gzipped file seems to be broken?

Came here to report the same thing. Doing :LspInstallServer on a .toml file gets me this output: "!/home/tuncay/.vim/plugged/vim-lsp-settings/installer/install-taplo-lsp.sh"

I am on Manjaro and my stuff is usually updated (including Vim and all plugins). Lsp Servers for other formats work fine work fine, so it is only this particular taplo server I can't install.
I have checked the latest installer. For m1/m2 Macs, the output of uname -m is 'arm64', which results in an incorrect download link being generated (with the filename 'taplo-full-darwin-aarch64.gz')
taplo installer is broken, and my environment is Darwin X86_64.
The reason is that taplo 13.0 release does not provide binary.

It seems that we need to build the source code.
