Encourage product teams to link to a specific docs version

[alexronquillo]

The products are sometimes linking to "current" or "next" docs, despite the product, itself, being versioned. This means when we cut a new docs version, this can create issues with broken redirects and the product linking to unexpected content.

For example, if version 8.8 of the product links to /next/ we need to support that redirect until 8.8 is no longer supported. This can be hard to detect and can also make maintenance tasks more difficult.

Acceptance criteria:

• See if this affects SaaS as well or just SM
• Suggest product teams change docs links to specific versions (/8.10/ instead of next)
