chore(lsp): set lower pylsp severity

Not sure to use "Information" or "Hint", and maybe settings["diagnostics_virtual_text"] should be more controlable so one can define

	vim.lsp.handlers["textDocument/publishDiagnostics"] = vim.lsp.with(vim.lsp.diagnostic.on_publish_diagnostics, {
		signs = true,
		underline = true,
		virtual_text = { require("core.settings").diagnostics_virtual_text, severity_limit = "Warning" },
		-- set update_in_insert to false bacause it was enabled by lspsaga
		update_in_insert = false,
	})

LGTM. Set it as info is ok for me.

It can be introduced in next pr to make diagnostics severity configurable for user.
