Telescope builtin browser_file is removed

[archite]

I find this a good bit easier:

local file_browser = require('telescope').load_extension('file_browser')
require('telescope.builtin').file_browser = file_browser.file_browser

The extra benefit is that it works for other plugins which expect the deprecated builtin.file_browser to exist.

Since file_browser has been completely removed from Telescope, I think the best course of action right now, would be to completely remove the ctrl-b functionality from this plugin. (other suggestions are welcome)

Perhaps it's possible to check if nvim-telescope/telescope-file-browser.nvim is installed and use it if so?
