V1 Wizard: Add search parameter for release selection

Adding an optional search parameter to the wizard like so:

/insights/image-builder/imagewizard?release=rhel8

results in the wizard being opened and RHEL 8 being pre-selected as the
release.

The Insights assistant chat bot will make use of this feature.
