Anaconda Distribution and Miniconda installer preset

[marcoesters]

Description/Purpose

Anaconda Distribution and Miniconda installers undergo a different release process than other dependencies that can be found on, e.g., GitHub or PyPi. Consequently, a custom-built renovate data source is needed to capture these installers.

This PR provides custom data sources and package rules for both Anaconda Distribution and Miniconda installers. Additionally, documentation is provided to show users how to incorporate this preset and to explain the complex transformation templates for this preset.

Expected Impact

Developers will be able to keep dependencies on Anaconda Distribution and Miniconda installers up-to-date using renovate. The default renovate managers are currently not capable of accomplishing this.

Multiple installers architectures in one repository are bundled into one pull request. However, Anaconda Distribution and Miniconda will be split.

Changes

• Add a preset for Anaconda Distribution and Miniconda installers
• Add documentation describing how to use the preset and explaining the transformation template
• Remove Dockerfile documentation: the regex manager has been removed from defaults.json and the use case is misleading since Miniconda installers are not available when conda is published on GitHub.

LGTM

I have one suggestion: I think it would be beneficial to name the files:

• docs/anaconda-installers.md
• anaconda-installers.json

and also change the reference in the doc in L11 to make sure these files are about our anaconda installers and not some other (generic) installers. For users this might make it easier to understand what installer is meant here, especially in our generic renovate-config repository which is used for different kinds of things.

Good idea! It's always better to be more explicit
