enable deprecated warnings, minimum neovim version 0.9, harden support for greater versions about nvim-tree.lua HOT 3 CLOSED

We shouldn't be concerned about development versions prior to 0.10. We should support:

• latest release (0.10)
• previous release (0.9)
• current nightly versions (relatively new, 0.11-dev, without many (any?) guarantees)

I couldn't find a reliable way to detect dev versions; 0.9 is now the minimum and it's up to the user to deal with issues with dev versions.

I did put off that diagnostic breakage until 0.11 as more users will likely raise issues. https://github.com/nvim-tree/nvim-tree.lua/pull/2788/files#diff-b4d683774fedaa8bdc2f7107576331513b01888c09ab2fcfd44468ef976c1b08

That works for me. We can continue to use the simple vim.fn test and keep the code clean.

The only issue is users on 0.10 dev versions (debian!), which do break. Could we just show a startup warning like "...proceed at your own risk..." ?
