[Bug] telescope theme deprecation notice shown continuously

[akinsho]

Describe the bug
The recent telescope theme deprecation warning is shown continuously because the telescope theme object itself actually has a key called theme, so this wrongly reports that a user hasn't migrated despite having done so.

System information

• OS: [windows/linux/mac] macOS
• Neovim version: nightly
• Is this related to a specific vim.ui.select backend? If so, which one? Telescope
• Dressing config:

use {
      'stevearc/dressing.nvim',
      after = 'telescope.nvim',
      config = function()
        require('dressing').setup {
          input = {
            insert_only = false,
            winblend = 2,
          },
          select = {
            telescope = require('telescope.themes').get_cursor { -- <--- This function returns an object with a theme key
              layout_config = {
                height = function(self, _, max_lines)
                  local results = #self.finder.results
                  return (results <= max_lines and results or max_lines - 10) + 4 -- 4 is the size of the window
                end,
              },
            },
          },
        }
      end
