Support multiple version of trestle docs using `mike` or similar on mkdocs website.

Issue description / feature objectives

As trestle grows in complexity it's likely that multiple versions of the documentation is required, as the trestle website also supports API docs. mike allows multiple versions to be displayed correctly with a drop down.

Caveats / Assumptions

• mike is used

• Versioning (until stability) is based off of every unique sem-ver release

• no branch based builds.

  Completion Criteria

• Trestle documentation website correctly releases along with a version published to pypi.

• Default version correctly points to latest

I´m re-assigning this to me instead, but I don´t see it happening for next milestone as this doesn´t seem to be a high priority item for now

Hey @AleJo2995 if you haven't done much I can take this on.

[butler54]

Got a question on this with respect to the structure, in particular 'default's for versions.

In scope:

• each release has a version of the documentation
• The default view is the latest released code
• Develop branch is also included as 'Develop' but it is not default. This release will get automatically updated each branch Out of scope:
• Branch / PR based builds of the website.

Go ahead @butler54 , you can take it on 👍 And yes, all the statements above are true, at least that´s how I see it.
