Investigate source code repository providers and package registries for potential tooling sources

[SensibleWood]

User Story

As a user of tooling data I want to gather tooling data from all significant source code repository providers

Detailed Requirement

The current data sources tend to focus - not necessarily intentionally - on GitHub. It would be great to expand the search to take in - for example - Gitlab, Bitbucket, npm, etc to gather new tools, data sources, and additional metrics (note the APIs.guru openapi3 source already tapped into some sources).

Research and analysis therefore needs to be undertaken to work out:

• What sources are readily available.
• How to normalise them across what we already have.
• What opportunities there are to tempt tooling providers to publish their tools (through tagging etc.) so we can consume.

This should all be collated in a Google Doc (or similar) so the work can then be broken down into issues.
