Subject: [PATCH 5/9] refactor: let updaters define the files they want to run
 on (#233)

This change reverses the responsibility for which files the updaters are
run on. Now each updater can specify the list of files and wether the
files should be created when they do not exist yet. This simplifies the
handling of each update in releaserpleaser.go, as we can just iterate
over all updaters and call it for each file of that updater.

Also update the flags to allow users to easily define which updaters
should run.

+# Updaters
+
+There are different updater for different purposes available.
+
+They each have a name and may be enabled by default. You can configure which updaters are used through the
+`updaters` input on GitHub Actions and GitLab CI/CD. This is a comma-delimited list of updaters that should be enabled, for updaters that are enabled by default you can remove them by adding a minus before its name:
+
+```
+updaters: -generic,packagejson
+```
+
+## Changelog
+
+- **Name**: `changelog`
+- **Default**: enabled

+- **Name**: `generic`
+- **Default**: enabled
+
+This updater can update any file and only needs a marker on the line. It is enabled by default.
+
+Learn more about this updater in ["Updating arbitrary files"](../guides/updating-arbitrary-files.md).

+## Node.js `package.json` Updater
+
+- **Name**: `packagejson`
+- **Default**: disabled
+
+This updater can update the `version` field in Node.js `package.json` files. The updater is disabled by default.

Subject: [PATCH 8/9] fix(github): duplicate release pr when process is stopped
 at wrong moment (#236)

In a timing issue, the release pull request may be created but the
releaser-pleaser labels not added. On the next run releaser-pleaser
then creates a second release pull request. We try to reduce the chance
of this happening by checking the context cancellation at the top, and
if its not cancelled we run both API requests without passing along any
cancellations from the parent context.

Closes #215
