What happened?

Description

Entry type names appearing in conditional builders are prefixed with the name of the section (or, one of the sections) they have been added to.

This doesn't make sense on Craft 5, considering entry types have been decoupled from sections (and have unique names), and it's especially confusing in cases where a single entry type has been added to multiple sections.

The issue appears to affect conditional builders in both entry index filters and field layout designer slideouts:

Steps to reproduce

Expected behavior

Entry type names should display in conditional builders without the name of any associated section prefixed.

Actual behavior

Conditional builder Selectize fields prefixes entry type names with (one of) the section(s) that entry type has been added to.
