New bullets

Is there any interest in adding new unicode bullets? Right now the ones I would like would be for questions and TODOs. Something like this: ``` r cli::cli_bullets(c("?" = "This is a question", "[]" = "This is a TODO")) ``` With the symbols (in red): ``` r cli::symbol$fancy_question_mark #> [1] "❓" cli::symbol$checkbox_off #> [1] "☐" ``` ^{Created on 2025-07-21 with [reprex v2.1.1](https://reprex.tidyverse.org)} I'm happy to make a PR if the answer is yes.
