Pylyzer requires Erg as dependency, suggest adding this info

[fishBone000]

Description

Pylyzer needs Erg to function correctly, whose path to its binary and libs should be stored in env var $ERG_PATH:

[ERROR][2024-11-11 12:08:17] .../vim/lsp/rpc.lua:770 "rpc" "/home/fishbone/.local/share/nvim/mason/bin/pylyzer" "stderr" "\27[91m[ERR] ERG_PATH not found\27[m\n"

I can resolve this by extracting tar from Erg release to my ~/.erg, then export env var by vim.fn.setenv("ERG_PATH", vim.fn.getenv("HOME") .. "/.erg")

However no such info regarding Erg is provided in lspconfig-all. I suggest adding this, or even better, adding erg_path option to let lspconfig handle exporting the env var automatically.

File structure of Erg tarball:

tar -tf erg-x86_64-unknown-linux-gnu.tar.gz                                                                                                                                     exit 1  47s
