Reverts #1945

Fixes element-hq/element-web#6967

This issue requires a refactor of the code to be able to generate both Textual and Richer (Element) representations of events.

Would be good to understand what's gone wrong here and how this has ended up changing the events that get generated.

This also reverts a lot of translations that were done for the PR. Losing those would be a pain for translators as they'd have to re-translate. Can we keep them in?

[dbkr]

oops, sorry luke. I Think all the translation changes were michael's script though.

[t3chguy]

@lukebarnard1 the only i18n changes I see are the ones I made using my script (replacing %(...)s with <...>)

things using TextForEvent rightly assume it returns strings, but by throwing JSX in there it ended up spitting back React Elements so now things started printing it as [Object object] instead

(Things like Notifier which is not capable of rendering React Elements)
the [Object object] in timeline is probably an issue internal to the original PR

[dbkr]

ah right

[t3chguy]

this'll need more thought and a way of either getting a Textual Representation or a richer React Element one
