[outreachy] Registry: inline help

[svrnm]

Outreachy task for @bhekidaweti

Thank you for filling out the user experience report, please provide the following improvement via a PR:

Like I mentioned, providing a little explanation further would help first time users understand clearly what the app is about.

Come up with 1 or 2 ideas how inline help could be added to the page. This is not about adding a link that leads to a page explaining everything, but about small interactive elements that show how one can use the registry, and what they can expect from the registry. We can then discuss what you can implement in a PR.

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
