feat: add gg and G to default mappings

[goolord]

since we have scrolling now, I think these are sensible default mappings :)

Generally LGTM thanks :)

Could you please make one change prior to merging though?

telescope.nvim/lua/telescope/actions/init.lua

Lines 104 to 127 in ba41f0e

	function actions.move_to_top(prompt_bufnr)
	local current_picker = actions.get_current_picker(prompt_bufnr)
	current_picker:set_selection(
	p_scroller.top(current_picker.sorting_strategy, current_picker.max_results, current_picker.manager:num_results())
	)
	end
	--- Move to the middle of the picker
	---@param prompt_bufnr number: The prompt bufnr
	function actions.move_to_middle(prompt_bufnr)
	local current_picker = actions.get_current_picker(prompt_bufnr)
	current_picker:set_selection(
	p_scroller.middle(current_picker.sorting_strategy, current_picker.max_results, current_picker.manager:num_results())
	)
	end
	--- Move to the bottom of the picker
	---@param prompt_bufnr number: The prompt bufnr
	function actions.move_to_bottom(prompt_bufnr)
	local current_picker = actions.get_current_picker(prompt_bufnr)
	current_picker:set_selection(
	p_scroller.bottom(current_picker.sorting_strategy, current_picker.max_results, current_picker.manager:num_results())
	)
	end

For these three actions, we would need to replace

  local current_picker = actions.get_current_picker(prompt_bufnr)

with

  local current_picker = action_state.get_current_picker(prompt_bufnr)

as the former by now is deprecated.

We often abstain from adding new default mappings; however, I'd vote in favor to include this one. Once you've made the changes and no other member makes a comment, I'd merge some time tomorrow or the day after to give them sufficient time to chime in, if that's ok :)

The functions are currently mapped to H/M/L because that what they previously did. I am fine with these mappings but we need new functions that allow us to jump to high, middle and low of the current screen.

Also we need a mention of them here https://github.com/nvim-telescope/telescope.nvim#default-mappings

ah, I didn't realize that the behavior of those keybindings even changed with the scrolling PR. I can try to fix them, though this is getting mildly out of the scope of this pr imo

[Conni2461]

This is out of scope of this PR. Just wanted to mention it. Updating readme is enough. After that i would merge it. Thanks for the PR :)

If you wanna write these new functions that would be awesome :)
