Resolve the need to manually maintain the "Contribute to docs" link destination

[MariaVrachni]

Summary

The footer of maas.io contains a link "Contribute to documentation" which takes the user to the Writing Guide (currently @ https://docs.ubuntu.com/maas/2.1/en/contributing-writing). The guide is linked to a MAAS version and with any version updates we need to manually update the link on the footer. One solution would be to move the guide to a subset of docs that is not linked to any versions. Another solution would be to automate the link update with any new docs update.

The ideal solution to this problem is outlined in #99 (comment), and mainly depends on Redirect to latest version automatically being solved in docs.ubuntu.com, and ideally also two other issues being solved:

• Provide a mechanism for creating redirects in documentation sets
• "Not on latest version" indicator?

It would be wonderful if the MAAS squad could take on the task of prioritising and pushing this so those issues get addressed =)

To be clear, my concern goes beyond this specific link. The Doc team should be able to link to the current stable version of any MAAS docs page without having to hardcode a version.

[nottrobin]

@pmatulis I agree. I believe the issues I've mentioned address exactly that general problem. I'm just using MAAS as a vehicle to get it prioritised.

OK, but maybe the issue title should be changed.

@pmatulis Feel free to change the issue title as you find appropriate.
