Add truncation markers to our blog posts

[rhamzeh]

We should add truncation markers (<!-- truncate --> or {/* truncate */}) for to our blog posts

1. It prevents possible SEO problems
2. If we don't manually add them docusaurus v4 will do that automatically, and the automatic ones may not be what we would prefer

See: facebook/docusaurus#9691

Hi @rhamzeh,
I’d like to work on adding truncation markers ( or {/* truncate */}) for our blog posts as discussed in issue #1026. Could you please assign it to me? I’ll make the changes locally and submit a PR for review.

Thanks!
