A follow-up to #4246 which was insufficient.

Closes #2028 

- Refactor: move fixtures to corresponding directories
- Delete unused fixtures

Resolves: #3328 

The code to get a list of releases was not using the RENOVATE_ENDPOINT when the npm modules it was fetching releases for had it's git repository on github enterprise.

Closes #3079 

Adds the library `linkify-markdown` to actively linkify urls, issues and usernames so that they can then be linked to the renovatebot redirector for github.

This PR follows up and fixes #1968

The previous PR didn't behave correctly as it was expecting Github Enterprise to ALWAYS been configured and that the github.com token was available in the `GITHUB_COM_TOKEN` env variable.
But for non GHE project `GITHUB_COM_TOKEN` is not defined and github.com token is available at the `GITHUB_TOKEN` env variable instead.

This updated PR fix this issue and avoid further problems by prioritising `github.com` over GHE.
Now the code is NOOP if no `GITHUB_ENDPOINT` is configured.

If it's configured, instead, now the codes assumes that, by DEFAULT, a dependency is hosted on `github.com` so it removes `GITHUB_ENDPOINT` and use `GITHUB_COM_TOKEN` as Github token immediately.
They are restored only if needed, when a dependency is hosted on the provided GithubEnterprise.

This reverts commit f2fb2e6b.

Improves changelog detection algorithm to look for different upper/lower case options as well as alternative filenames like `History.md`.

Resolves #1754

Resolves #1709

Parses `CHANGELOG.md` for first or second-level markdown headings matching versions. Supports GitHub-only source repositories for now.

Closes #1470 

Detects and embeds release notes found on GitHub when an npm dependency specifies a GitHub repository as its source and that repository has made use of the "Releases" feature.
