Metadata Editor - Translated text in the templates buttons are cropped

### Steps to reproduce

1. Choose a Language in the Preferences - e.g. French
2. Load a Project
3. Open the Metadata Editor
4. See the cropped texts in the buttons

### Expected behavior

Buttons should be large enough to contains the translated texts.

### Actual behavior

_No response_

### Audacity Version

6fadc7a

### Operating system

Windows

### Additional context

_No response_

Start by reproducing the issue in Audacity on Windows: choose French in Preferences, load a project, and open the Metadata Editor. Locate the template toolbar and inspect how its button sizes respond to translated labels; done means the labels are fully visible without cropping in the reported language and the surrounding toolbar still works.
