fix(#2370): Better "y/N" prompts (#2377)

* Changed the default y/n prompt to default to N in most cases(all delete cases) and made it so that the copy paste same name conflict defaults to R(ename)

* Removed all No conditions as they are not used and not needed

* Made item_short into lowercase and also fixed prompts in dressing.nvim and telescope-select.nvim

* Fixed the exception which occurs on pressing esc in the prompt and also made rename to be blank or r.*/R.*
