---@brief [[
--- Telescope Builtins is a collection of community maintained pickers to support common workflows. It can be used as
--- reference when writing PRs, Telescope extensions, your own custom pickers, or just as a discovery tool for all of
--- the amazing pickers already shipped with Telescope!
---
--- Any of these functions can just be called directly by doing:
---
--- :lua require('telescope.builtin').$NAME_OF_PICKER()
---
--- To use any of Telescope's default options or any picker-specific options, call your desired picker by passing a lua
--- table to the picker with all of the options you want to use. Here's an example with the live_grep picker:
---
--- <code>
---   :lua require('telescope.builtin').live_grep({
---     prompt_title = 'find string in open buffers...',
---     grep_open_files = true
---   })
---   -- or with dropdown theme
---   :lua require('telescope.builtin').find_files(require('telescope.themes').get_dropdown{
---     previewer = false
---   })
--- </code>
