ui: update @rjsf/antd and use tooltips for descriptions

[miguelgrc]

Feature request

What is the expected behavior?
@rjsf/antd is updated to the latest version and tooltips are added to the PropKeyEditor and form fields.

What is motivation or use case for adding/changing the behavior?
There's this PR for @rjsf/antd which will allow to show descriptions as antd tooltips. We can take advantage of this in the PropKeyEditor and also by giving users the option to define a tooltip for their fields.

How should this be implemented in your opinion?
Update the dependency to the latest version. If it needs antd v5, it should be updated as well. Change descriptions in the PropKeyEditor to tooltips (at least in the cases in which it makes sense) and add a "Tooltip" field to let users specify a tooltip.

Are you willing to work on this yourself?
yes
