fix: version view breaks when tab field has function for label (#13415)

### What?

Fixes an issue where using a function as the `label` for a `tabs` field
causes the versions UI to break.

### Why?

The versions UI was not properly resolving function labels on `tab`
fields, leading to a crash when trying to render them.

### How?

Tweaked the logic so that if the label is a function, it gets called
before rendering.

Fixes #13375
