Make Twitter card's content value configurable

[pfertyk]

Hi!

First of all: I would like to thank you for a wonderful Hugo theme! It has everything I need for my website :)

I have switched to Hugo after using Pelican, and I wanted to keep some things consistent with the previous version (e.g. URLs of articles, RSS file path, etc). This theme allowed me to configure practically everything except for Twitter cards. The configuration I had in Pelican used content="summary" while PaperMod uses content="summary_large_image".

I realize that it's not an urgent issue, but with only a square photo (of my face) available for my blog posts, the large image version looked really weird ... I ended up forking this repo and changing a single line of code: pfertyk@a6c4a3c

This works perfectly for me now, but do you think that maybe in the future PaperMod could have a config option to switch between different content types?

Hi, yes that's the default with all hugo themes: https://github.com/gohugoio/hugo/blob/a6e84391760ca3786bf580344e2a013ac54b4b4a/tpl/tplimpl/embedded/templates/twitter_cards.html#L3

Right now unsure how to solve this without adding a config variable. Lets see

I would be 100% OK with a config variable ;) I'm not sure how many content options are there for Twitter cards, but maybe it could just be a flag (use_summary_large_image, default true) ?
