Provide novel tooling for regulatory needs

Description of feature

We are currently a group of people working on #regulatory topics and have several needs that we consider to be of value for the wider community. This includes tooling that can create a snapshot / nf-core regulatory report for a certain pipeline that contains information that should be accessible online but needs to be snapshotted:

• Number of users of that pipeline
• Number of contributors
• How many releases per year? How many releases within the last 6 months?
• How many minor/major releases this year?
• Link to versioned documentation / user documentation
• Github stars, clones per time units
• Review policies set accordingly for branches
• Changelog of pipeline
• Utilized containers + software versions (?)
• pipeline version

(none of this intends to be complete)

Most of this can be done relatively easily, but we think it would be great if e.g. something like:

nf-core pipelines regulatory

exists and then generates already the information snapshot that we will always need, almost independent of the standard we try to tackle.

Start by reviewing the proposed nf-core pipelines regulatory command and the listed snapshot fields, including releases, users, contributors, documentation, GitHub metrics, review policies, changelog, containers, and software versions. Define the reporting scope and regulatory standards first; done means an agreed, repeatable snapshot design rather than a partial collection of metrics.
