fix(lua-language-server): root directory pattern #3322

Problem:
Looking at the code for root dir detection for `lua_ls`:
https://github.com/neovim/nvim-lspconfig/blob/9bda20fb967075355f253911bc066a8b5a03c77e/lua/lspconfig/server_configurations/lua_ls.lua#L17-L27
I was surprised that finding the git ancestor has lower priority than
the `lua/` subdirectories (which, btw, is not mentioned in docs).

Consider the following directory structure:

    HOME/
    ├─ workspaces/
    │  ├─ lua/
    │  ├─ python/
    │  ├─ work/
    │  │  ├─ SomeProjectWithLuaFiles/
    │  │  │  ├─ .git/

The `lua/` and `python/` directories contain some miscellaneous
language-specific projects I sometimes work on. The project directory
under work/ also contains some lua files. I expected the `.git` directory
in the project to ensure that the project root dir is correctly detected
to be `…/SomeProjectWithLuaFiles`. But since the [search for the `lua/`
subdirectory](https://github.com/neovim/nvim-lspconfig/blob/9bda20fb967075355f253911bc066a8b5a03c77e/lua/lspconfig/server_configurations/lua_ls.lua#L22)
is done first, my LSP detects `HOME/workspaces/` as the root directory.

Solution:
Search for the git ancestor before looking for the `lua/` subdirectory.
Return the longer root path if both a `.git/` and a `lua/` ancestor are found.
Fixes #3165
