Create a how-to on how to test a pre-release version of Django

[Sarah Boyce]

In an episode of DjangoChat, there was a discussion that we need more testers of pre-released Django versions. I am in full agreement that early testers are wonderful and the more the merrier 😊

In order to encourage this, there was a proposal to have a how-to page, as there may be folks who want to do this but don't know how.

We can then link to this in our blog posts when pre-releaes are published.

This how-to probably should link to the ​how-to upgrade Django page, as being on the latest released version is a reasonable prerequisite.

I have also proposed us having a scheduled job to test against djangoproject.com (​https://github.com/django/djangoproject.com/issues/2391) which we may be able to link to in order to give folks an example implementation of testing against Django's main branch.

Thank you Sarah for taking the time to create the ticket! I'm in full agreement :-)
