[outreachy] Registry: Improve visibility of teaser text

[svrnm]

Outreachy task for @MercyCherop

Based on your user experience report, please provide the following suggested improvement via a PR:

The text just above the search bar seems to be important information and though it has been highlighted it still feels a bit hard to find. [...] I feel the text should be moved elsewhere the is more visible and have its font size slightly increased.

Please provide a suggestion how the teaser text can be made more visible, appealing and easier to find. Feel free to be creative using not only text improvements, but any kind of visual improvements that come to your mind

Note: This is an assigned issue for a participant that has completed the user experience report, if you are an outreachy participant as well, find instructions here: #5290
