Hide the parser docs from the current docs version

[hans-notifi]

• Update to Docusaurus 3.3.2
• Update to clsx 2.1.1
• Cut a Release version that contains our current docs, remove all other versions
• Hide the Parser docs from the Release version - since they discuss a feature that has not been publicly released and might change, wait to feature these docs until the feature is ready. Retain these docs in the vNext docs so they can continue to be reviewed.
