Create release of elixir-ls

git clone https://github.com/elixir-lsp/elixir-ls.git elixir-ls pushd elixir-ls git checkout v0.17.10 # or some other release mix deps.get MIX_ENV=prod mix compile MIX_ENV=prod mix elixir_ls.release2 -o release popd

Then a language server script file should have been created under elixir-ls/release/language_server.sh.
