Try and use klaro v1.2.2 to fix the previous issue with Consent Manager style

[jupiter007]

Describe the bug
We previously worked on a bug where the Consent manager style was not correct. We implemented a workaround here: #725

Since then, Joel said that he fixed an issue with klaro, and released v1.2.2.

We can see if implementing this new version of klaro-ui will allow us to remove the workaround.

To Reproduce
Steps to reproduce the behavior:
Currently, with the workaround, you won't be able to see the issue. You will have to go into app/javascript/application.js and add back the import "klaro-ui/dist/css/klaro-ui.css" line and remove the cookie-notice style from app/assets/stylesheets/dmptool/_klaro.scss in order to check whether the new version of klaro-ui addressed the bug.

Expected behavior
The Consent manager should look like the one on https://cdlib.org/
