Custom FONT_DIR did not take effect

[xiaoyao9184]

The FONT_DIR was overridden by an external environment variable,
but the final RECOGNITION_RENDER_FONTS still uses the old value.
Perhaps I should override RECOGNITION_RENDER_FONTS as well,
or make RECOGNITION_RENDER_FONTS a dynamic property,
like

surya/surya/settings.py

Lines 88 to 91 in a8b34c4

	@computed_field
	@property
	def MODEL_DTYPE(self) -> torch.dtype:
	return torch.float32 if self.TORCH_DEVICE_MODEL == "cpu" else torch.float16
