Without this, it's possible that the helm chart documentation
contains the `image tag` version which might not be equal to
the version in the helm chart, as it's only an example.

This is a confusing, so instead we should use make to edit the
application version everywhere.

This fixes it by updating the Makefile to modify text of the
chart's README using a regex looking for something similar to
a version; then I used the updated makefile to edit the README,
which in turns requires a bump of the version of the chart
itself.

Bumping the helm chart with minor version bump, due to minor
version bump of the kured appVersion.

Without this patch, chart linting will fail: more than two
spaces are needed before a comment in the helm chart values.

This fixes it by adding one more space, and move the whole block
of comments for consistency.

This ensures we bump the code for 1.20.
It updates the testing to ensure kured works on a 1.20 cluster,
removes the testing on 1.17 (as it is now deprecated).
Libraries remain on 1.19, to avoid breaking 1.18 clusters.

	- update chart versions
	- update release documentation
	- Christian and David are the chart maintainers

	Drop bit in the docs about updating image tag - not necessary
	if you use the instructions.
