Uncommenting force_color_prompt in .bashrc file doesn't work

**Describe the issue**
Using a fresh instance of the [Debian 10.4 (Minimal) .utm file](https://mac.getutm.app/gallery/debian-10-4-minimal), this is listed in the .bashrc file:
```
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes
```
The only change to the above that I made was uncommenting `force_color_prompt`. After this I have tried a reboot and re-sourcing the .bashrc file. Nothing I have found has successfully enabled the color prompt. I am aware that there are other changes I could make to the .bashrc file (or other files) to get a color prompt working - but it was my understanding that all I should have to do, with a completely fresh install of Debian, is un comment the `force_color_prompt=yes` line. But I'm pretty new, so I could be mistaken. I wasn't exactly sure if this was an issue with me, or Debian, or UTM; but I figured I'd start here.

**Configuration**
* UTM Version: 3.2.4 (58)
* OS Version: 12.5
* Apple Silicon: M1 MBP

UTM is awesome! And thanks in advanced for any feedback!
