Guard.nvim should support lint on FileType *

[UnderCooled]

ft('*'):lint(...)

In the screenshot, autocmd is generated fine:

But it won't be execute on :GuardFmt or on file save.

guard.nvim/lua/guard/lint.lua

Lines 13 to 16 in 4645785

	if not ft_handler[vim.bo[buf].filetype] then
	return
	end
	local linters = ft_handler[vim.bo[buf].filetype].linter

I think this if check skips the linter defined in ft('*').
