It keeps returning 5xx errors and looks ugly

The link to the configuration docs was broken. Fixed it.

If attempting to create a branch and it already exists, or attempting to update a branch and it no longer exists, then we abort.

chore: update dependency eslint to v4.17.0

Removes the GitHub-only check when cleaning/pruning branches.

Previously, our GitLab API library was checking if a a branch existed first before trying to create it. But due to caching, a branch we'd deleted ourselves still showed up as existing, so then there was no branch to update the files in. Skip this check and use try/catch for creating branch instead.

Fixes #1468

This reverts commit fb1c291b.

fix: unset ghe token before calling changelog

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.

List versions and their commits in PR bodies in the order they were made (oldest to newest).

Assuming `sharebe` -> `shareable`

`autoMerge` -> `automerge`

Closes #1461

If a dependency has name starting with `@types/` and no repository url returned from the npmjs query, we manually set a URL pointing to the DefinitelyTyped repository.

Adds a new feature to limit the number of concurrent branches/PRs to have open at any one time. Defaults to 0 (disabled), set it to a positive integer to enforce that limit.
