Docs: update extension versions so correct file is served by jsDelivr

[scrhartley]

Description

Update the links to extensions following PR #171 in extensions repo. With the latest versions the correct file is received (not the ESM one) and integrities have been updated accordingly. Not all integrities have been updated since not all extensions have actually changed other than their package.json files and their integrity on the site was for the file that should have been served. For completeness, included idiomorph extension in the updates even though its link is from UNPKG. I left it with UNPKG since that's what the Idiomorph repo uses in its docs.

Corresponding issue: #3380

Testing

Visual inspection using Zola and also the jsDelivr in browser to check they are now the correct ones.
