Is your feature request related to a problem? Please describe.
I'd like to select a query, whether single or multiple selections.

Currently, for single selection, the <tab> key is bound to select a query, and this key binding is hard coded.
For multiple selection, there are no key bindings to select a query, and <tab> is used to toggle selection.
I'd like to use same key (e.g. ctrl-y) to select a query for both single and multiple selections.

Describe the solution you'd like
Remove SuggestionType::SingleRecommendation and make SuggestionType::SingleSelection (--prevent-extra option) as default.
Allow to forward --bind options to fzf.
User can select a query by binding print-query action to arbitrary keys.

Example:

config.yaml

finder:
  overrides_var: --reverse --height 16 --cycle --bind 'ctry-y:print-query'

cheatseet

% sample
# sample
echo <word>
$ word: echo -e 'one\ntwo\nthree'

# multiple
echo <words>
$ words: echo -e 'one\ntwo\nthree' --- --multi --map "tr '\n' ' '"

# prevent extra
echo <exact_word>
$ exact_word: echo -e 'one\ntwo\nthree' --- --bind 'ctrl-y:ignore'

Example of print-query actions in fzf are following.

echo -e 'one\ntwo\nthree' | fzf --bind 'ctrl-y:print-query'
echo -e 'one\ntwo\nthree' | fzf --multi --bind 'ctrl-y:print-query'
echo -e 'one\ntwo\nthree' | fzf --bind 'ctrl-y:print-query' --bind 'ctrl-y:ignore' # second binding invalidates first binding

I confirmed with fzf version 0.55.0.

Describe alternatives you've considered
In fact, selecting query can be achieved in the current implementation by setting the following

config.yaml

finder:
  overrides_var: --reverse --height 16 --cycle

cheatseet

% sample
# sample
echo <word>
$ word: echo -e 'one\ntwo\nthree' --- --prevent-extra --fzf-overrides '--reverse --height 16 --cycle --bind "ctrl-y:print-query"'

# multiple
echo <words>
$ words: echo -e 'one\ntwo\nthree' --- --multi --map "tr '\n' ' '" --fzf-overrides '--reverse --height 16 --cycle --bind "ctrl-y:print-query"'

# prevent extra
echo <exact_word>
$ exact_word: echo -e 'one\ntwo\nthree' --- --prevent-extra

This approach is annoying because it requires the --prevent-extra and --fzf-overrides options.
