Docs: Update README with full config from init.lua

The `README.md` file was missing the `filetypes` and `autostart` configuration options in the `init.lua` example, and also lacked the more robust `LspAttach` autocmd for keymappings.

This change replaces the `init.lua` example in the `README.md` with the more complete and accurate one from `plugin/nvim/lua/pcc/init.lua`, making the documentation consistent with the implementation and best practices.
