Add allow_file_downloads param to allow downloading image/video/audio media in chatbot

[hannahblair]

Description

We were never (iiuc) showing the download button in media messages in chatbot. I'e added an allow_file_downloads (default is false) param in case it's not actually wanted by certain users. Let me know if there's a better solution here!

I've also tweaked the padding so that components dont have an unnecessary padding that only text needs (see screenshot).

to apply padding only to text message content

removing these stories and consolidating their variants with other stories to reduce snapshot usage

Nice! Is it possible to respect the show_download_button parameter passed to the component instead of adding a component to the chatbot? I'm confused as to why the download button shows up when passed to the component but only when like/dislike is enabled (quoting from the issue - haven't verified!)

Looks great, thanks for the cleanup also! In response to what the issue is saying, it's only if there is a like listener that it appears in the like row automatically. I think we should remove it from the like row, and have it on media by default?

Thanks for reviewing @freddyaboulton and @aliabid94!

Yeah I forgot about it in the lower panel! It seems our logic to check when to show the panel (show: show_like || show_retry || show_undo || show_copy_button) was incomplete. Nonetheless, I'll remove the param and we'll just apply it by default.
