Implement a popup list showing the quarkus versions returned by /api/streams

[cmoulliard]

• Implemented a popup list showing the quarkus versions returned by /api/streams
• The popup list is created from the list of the streams and set the suffix (RECOMMENDED) for the version recommended. When the version is not FINAL, then the suffix is also added (example: CR2)
• See: Issue: https://github.com/q-shift/backstage-plugins/issues/50

TODO: If the user returns back to the screen where they selected the value, then the default value is displayed instead of the previously selected :-(

I did a change to the code (commit - 9cdb761) to introduce a selectedVersion which is used as defaultValue instead of defaultQuarkusVersion. Unfortunately we got this error when a user select a different value from the list:

useControlled.js:31 Material-UI: A component is changing the default value state of an uncontrolled Autocomplete after being initialized. To suppress this warning opt to use a controlled Autocomplete.
