System locale is not set when changing "Language", "Formats" and "Input Sources" fields in the "Region & Language" pane of Settings
I've set the Language on my Pinephone to "English (United Kingdom)", the Formats to "United Kingdom" and the Input Sources to "English (UK)". However, I note that no locales have been set following this. Running `locale` from the terminal results in the following errors:
```text
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
```
I have attached the current output to the `locale` command in a text file:
[locale.txt](/uploads/6b31e6d0a59dcd2ada04a0716fecf5c7/locale.txt)
