docs: minimal reproduction documentation

[HonkingGoose]

Changes:

Create a document in the docs/development folder that:

• explains what a minimal reproduction is
• tells why we need bug reporters to create a minimal reproduction
• has tips to make a good reproduction repository

Context:

Closes #8099.

Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please tick one)

I have verified these changes via:

• Code inspection only, or
• Newly added unit tests, or
• Unit tests + ran on a real repository

@rarkins, I have some questions about things you said in #8099

what a minimal reproduction is, with examples and counter-examples. we could link to some real examples, although it's always possible that users could delete them eventually once the problem is solved

How about we create a renovate/reproduction-examples repo, that contains example(s) of a good and bad reproduction.
That way we keep control of the content to which we link, and ensure the example repository is always available.

We can also try to help guide people about how to reproduce a problem with private repos or private registries enough that someone else can take it over.

This is not yet in the document, as I don't know what the text should describe.

---

I was going to write something like The Renovate team will help you if you get stuck making the reproduction repository.
But I don't know if that's what the team wants to do...
So I'm asking first: Does the Renovate team want to invest time in helping the bug reporter with the reproduction repository?
Or do we consider that to be just as bad "a waste of time" as debugging on a production repo?

[HonkingGoose]

@rarkins I think we also need to add a link to this new document from the issue templates where appropriate?

[rarkins]

@HonkingGoose yes, we can add it to the bug template. Maybe "Have you created a minimal reproduction repository?" and link "reproduction repository" to the docs page

[HonkingGoose]

I'll go and add that to the bug template then. 😄

[rarkins]

We can only do that once it's published.

[HonkingGoose]

Oh okay, I thought it would be good to include it in this PR, so that we don't forget later on. 😄

EDIT: Made a new issue to remind us of this work after this PR gets its final review and merge.
