Update Hungarian layout

[tenextractor]

See the contributing section in the readme for more detailed guideline: https://github.com/Helium314/HeliBoard?tab=readme-ov-file#guidelines
tl;dr (you should still read the full list though):

• make sure it's wanted
• a single thing only
• describe it properly
• re-use existing mechanisms / code
• low performance impact
• make it a draft if you still want to work on it
• don't do translation PRs

Further

• When the PR contains "fixes" , the related issue will be linked and automatically closed if the PR is merged (also works for other words like "fix", "resolve", "resolves", "closes", ...)
• If you add a keyboard layout, make sure you have read https://github.com/Helium314/HeliBoard/blob/main/layouts.md#adding-new-layouts--languages
• Please avoid force-pushing when doing changes. This way it's not possible which parts have changed since the previous state.

fixes #758

This massively changes the layout for every user of the Hungarian default keyboard, which will create issues by users to switch back to the old layout.
Feel free to create an additional layout, but please don't do such large changes to the app defaults based on a single person's preference.

Ok, I will add it as an additional layout.

[Helium314]

You could possibly make use of the recently added "language (extended)" string and set android:label="@string/subtype_generic_extended".
Do you need any help / information on how to add it as a new layout?

Thanks for the help. I was just busy on other things.
