Update camunda-platform-latest url references

[drodriguez-305]

Description

SM has removed the camunda-platform-latest directory from our repository, which means any links referencing it will no longer work. I've updated all affected links and adjusted them to point to the appropriate versioned directories.

When should this change go live?

As soon as possible as the directory has been removed in main.

• This is a bug fix, security concern, or something that needs urgent release support.
• This is already available but undocumented and should be released within a week.
• This on a specific schedule and the assignee will coordinate a release with the DevEx team. (apply hold label or convert to draft PR)
• This is part of a scheduled alpha or minor. (apply alpha or minor label)
• There is no urgency with this change and can be released at any time.

PR Checklist

• My changes are for an already released minor and are in /versioned_docs directory.
• My changes are for the next minor and are in /docs directory (aka /next/).

• My changes require an Engineering review, and I've assigned the Engineering DRI or delegate.
• My changes require a technical writer review, and I've assigned @camunda/tech-writers as a reviewer.

👍

Next time you can nudge us by adding a reviewer (either tech writers or distro team would work for a change like this).
