DO NOT MERGE yet because:

• some of the docs changes to use the new samples are still unsubmitted
• even after submitting the docs changes, we have to wait for all the translated pages to pick up the links to the new samples

@Rishabh-V assigning to you as I know you were looking into this. Only one tag remains in use.

Thanks!

[amanda-tarafa]

Never mind, it seems like all old tags have been removed. I'll rebase this PR and merge.

Closing in favour of #1949
