Support `abstract-title` for Typst format

[cderv]

I believe this could easily be supported like in HTML and some other formats by tweaking the template here

pandoc/data/templates/template.typst

Lines 62 to 66 in 0f29d81

	if abstract != none {
	block(inset: 2em)[
	#text(weight: "semibold")[Abstract] #h(1em) #abstract
	]
	}

so that Abstract is not hard coded.

Though it probably needs a Writer update to match behavior with Docx or HTML that supports this field

Makes sense. I think it could all be done in the templates.

I think it could all be done in the templates.

Looking at this closer, It seems Writers are currently setting some defaults and handling translation. Should translation of term works for Typst as HTML and Docx ?

Lines 916 to 920 in ddc66ca

	abstractTitle <- case lookupMeta "abstract-title" meta of
	Just (MetaBlocks bs) -> pure $ stringify bs
	Just (MetaInlines ils) -> pure $ stringify ils
	Just (MetaString s) -> pure s
	_ -> translateTerm Abstract

abstractTitle <- translateTerm Abstract

Yes, it would be good to use the translation of the Abstract term as the default value for abstract-title (which could be overridden). That's what is doen in the docx writer, as you see.
