fix(docker): change base image to `lua_ls`

The base image is changed from `anatolelucet/neovim` to `ubuntu:latest`
to fix the installation issue of `lua_ls`. With this change, manual
installation of NeoVim became necessary. It is handled by `tar` binary
installation method. Branch name can be changed in the `Dockerfile`. In
addition headless commands are fixed to wait for installation of
desired LSP list and TS list.
