Make it possible for users to navigate between different versions of the docs

[stevenjmesser]

Context

We'll be hosting two versions of the docs – v4 and v5 – simultaneously for a year.

What

Make it possible for users to navigate between two versions of the docs, so that they can use the docs relevant to which version of GOV.‌UK Frontend they're using.

Possible solutions

• Nest two folders inside the main directory, one for each version (e.g. /v4/ and /v5/; Prototype Kit team do this)
• Use a navigation component to navigate between the two versions, e.g. see top-left of the Tailwind CSS docs

Who needs to know about this

Tech writer/content designer, developers, interaction designer, product/delivery manager.
