See "System information" below.

### System information

Godot v4.1.4.rc (2d3b2abcf) - Windows 10.0.19045 - Vulkan (Compatibility) - NVIDIA GeForce GTX 970 (NVIDIA; 31.0.15.2698) - Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz (8 Threads)

### Issue description

POT generation ignores tr() expression in dictionaries:
```python
var strDeclarer = { 'N':tr("North"), 'E':tr("East"), 'S':tr("South"), 'W':tr("West") }[declarer]
var strVulnerable = { 0:tr("none"), 1:tr("both"), 2:tr("NS"), 3:tr("EW") }[vulnerable]
```
Strings as tr() parameters do not show up in the POT file.

### Steps to reproduce
