Subject: [PATCH] refactor!(elixir): remove alchemist

BREAKING CHANGE: alchemist appears to be unmaintained and has reportedly
been replaced by elixir-ls and LSP (#5488). To restore your Elixir dev
environemnt, enable :lang (elixir +lsp) and install elixir-ls via your
package manager or 'M-x lsp-install-server'.

Close: #5488
