feat(readme): add configuration section with plugin links

	Adds a new "Configuration" section to the README.md file.
	This section provides direct links to the configuration of each plugin, whether it's located in the `init.lua` file or in a dedicated file within the `lua/kickstart/plugins` directory.
	This makes it easier for users to navigate and understand the project's structure.
