some plugins may be helpful

Thanks `yetone` for creating this awesome repo, I just move from my `.config/nvim` to this repo. It's so silky! I'd like to recommend this to my coworkers.

Here is some plugins for two features that may be helpful.
- git graph
- rust development

In `./lua/plugins.lua`, add:
```lua
-- for git graph
use 'tpope/vim-fugitive'
use 'rbong/vim-flog'

-- for rust
use {'nvim-telescope/telescope-ui-select.nvim' }
use 'simrat39/rust-tools.nvim'
use 'mfussenegger/nvim-dap'
```

In `init.lua`, add:
```lua
require('rust-tools').setup({})
```
