v0.17.3

Added

• Add support for collections of bundle references, e.g. type = list(bundle(<class>)).
  In terramate ui such an input is a multi-select over the bundles of that class.

Fixed

• Fix terramate ui crash when using specific input types that are not supported by a form.
• Fix inputs without a prompt block being dropped from the config when a bundle instance is reconfigured or promoted in terramate ui.
• Fix multiselect list changes being applied to the input form before confirmation in terramate ui.
