Add --set tag={productchartversion} to helm commnands (#5128)

`latest` being the default tag value can lead to troubles, especially on
MLM where latest is no longer added to the images. There is a code
change to change the default tag to the chart's appVersion but this will
be merged for the next releases. In the mean time, document to set the
tag value. (bsc#1271902)

Uyuni cannot use {productchartversion} as there is no semver2 tag for
the images, {productnumber} is the one to use for it.
