Neovim 0.11 warning because position encoding is omitted from make_position_params

Describe the bug

When vim-tabby requests an inline completion on Neovim 0.11, Neovim displays the following warning:

position_encoding param is required in vim.lsp.util.make_position_params. Defaulting to position encoding of the first client.

The warning appears because lua/tabby/lsp/nvim_lsp.lua constructs the inline-completion parameters without specifying a position encoding:

local inline_completion_params = vim.lsp.util.make_position_params()

Besides producing the warning, defaulting to the first LSP client could select the wrong encoding when multiple clients are attached to the buffer.
