Adress os-locale 6.0.0 breaking change

[TomaSajt]

Describe the issue you are having

The os-locale dependency has been updated in a recent commit from 5.0.0 to 6.0.2.

However there was a breaking change between major versions, which was that os-locale became a pure ESM package.

Changelog of os-locale 6.0.0
The package owner's proposed solutions for using the package with Electron

I did not notice this change, because of my saved preferences (in prefs.js the kbdLocale field), however, once I deleted my RIDE config directory, (or just the prefs file,) it couldn't start the interpreter, because of errors being thrown about not being able to require(...) ESM modules.

I think it is acceptable to revert the version of os-locale to 5.0.0
