fix: #2291 - removed flawed specific font (back to default fonts)

[monsieurtanuki]

Deleted files:

• OFL.txt
• PlusJakartaSans-Bold.ttf
• PlusJakartaSans-Regular.ttf

Impacted files:

• main.dart: removed font licence registering
• pubspec.yaml: removed specified fonts (back to default fonts)
• smooth_theme.dart: removed specified fonts (back to default fonts)

What

• Some non latin letters are not rendered at all on some devices (probably Android).
• A couple of issues were created from users comment, about Greek and Ukrainian.
• We used a specific font (JakartaSans)
• When we switch back to the default flutter font, we don't have this problem anymore.
• As the standard flutter font and the one we specified are very similar, there's no added value in trying to use a font that does not always work. Unless we enjoy getting 1 star review (I don't).

Ukraine/Ukrainian:

I guess it is the right thing to do, but we're loosing the unique identity
People seem to be complaining:

• Extended Cyrillic tokotype/PlusJakartaSans#18
• Remove from Google Fonts: Font is riddled with so many issues with no sign of fixes or active development tokotype/PlusJakartaSans#30

We should probably ask Quentin for a similar font replacement. Meanwhile, is there a way to disable it only for non-latin languages ?

[monsieurtanuki]

@teolemon What about merging this PR first, and find the bullet-proof font / the perfect font combo later?

I'm hyper sensitive to 1-star ratings, and if I think about the time and energy spent on the rest of the app, I find it a bit depressing to have users reject the app for legitimate reasons that would require an easy fix.

The changes look good and I totally agree with the 1 Star reviews
