🐞 Changing terminal font size in settings does not have immediate effect

### Description

Changing terminal font size in settings does not immediately change the terminal font like changing the editor font size does. After restarting CodeEdit the change is correctly honoured.

### To Reproduce

1. Go to Settings->Terminal
2. Disable "Use text editor font"
3. Change font size to 15
4. Close settings.
5. Result: Terminal font stays the same, no change is visible. (Except line height)
6. After restarting CodeEdit, the changed terminal font size is correctly used in the terminal window.

### Expected Behavior

1. Go to Settings->Terminal
2. Disable "Use text editor font"
3. Change font size to 15
4. Terminal font size in terminal window is changed immediately (like changing text editor font size)
5. Close settings.
