This patch should fix the current problem that the renovate
annotation is not picked up by renovate as intended, resulting
in not updating the image appVersion in the helm charts.

This patch increases the amount of MRs that can be open at the
same time, to improve batch updates, given the growing number
of software deployed by this repository.

This patch fixes the weird CPU limit on sidekiq which causes
various dashboards to be blown out of proportion.

This patch tries to improve reproduciblity by using a
`requirements.txt`, this should not only pin a version, but
also allow renovate to update it automatically on a regular

mastodon source link to new organisation.

This patch adds some basic, "nice-to-have" metadata to the Chart.

This patch fixes the missing declaration of defaults for the
container resources in the sidekiq deployment. Rendering the
explicitly set resource requests and limits unused.

This patch fixes the error that the for loop for the sidekiq
deployments fails due to mixing up the YAML documents as it's
missing a divider.

This patch switches to our own helm chart (fork), which should
be a bit more stable than upstream as well as moving quicker in
order to develop both this and the upstream chart.

This patch adjusts the helm chart to automatically to
automatically switch to strategy `Recreate` when deploying the
scheduler queue to a sidekiq container. This will prevent
accidental concurrent execution of it.
