feature: add support for folke/persistence.nvim plugin

[gelocraft]

This PR add support for folke/persistence.nvim as an alternative for tpope/vim-obsession for neovim.

As a neovim user myself, I love folke's work and only want folke's plugins when possible.

And for people who loves or use tpope/vim-obsession and can't get it to work with tmux-ressurect just add this on your config.

return {
	'tpope/vim-obsession',
	enabled = true,
	event = 'VimEnter',
	init = function()
		vim.api.nvim_create_autocmd('VimLeave', {
			pattern = '*',
			group = vim.api.nvim_create_augroup('Obsession', { clear = true }),
			callback = function() vim.cmd 'Obsession' end,
		})
	end,
}

This config that I pasted will only work if you are using folke/lazy.nvim as your plugin manager, and if not I don't know what to tell you but may god have mercy on you.

Closes #470
