[feature] Add extra opengraph meta tags (#4154)

# Description

> If this is a code change, please include a summary of what you've coded, and link to the issue(s) it closes/implements.
>
> If this is a documentation change, please briefly describe what you've changed and why.

Update our opengraph meta tag code stuff:

- Use `audio` and `video` types where appropriate.
- Include fall back to `image` types.
- Include `twitter:card=summary` or `twitter:card=summary_large_image` where appropriate (closes https://codeberg.org/superseriousbusiness/gotosocial/issues/2776)
- Include avatar description where possible.
- Include mime type for media.
- Set `modified_time` properly based on latest edit time.
