gwenhywfar: update to 5.10.2, remove -gtk; aqbanking: update to 6.5.4
https://github.com/void-linux/void-packages/pull/45360

Description:
#### Testing the changes
- I tested the changes in this PR: **briefly**

I tested this as part of the gnucash update, and everything seems to work fine. I did **not** test against the older version of gnucash, so this should only be merged after https://github.com/void-linux/void-packages/pull/43386.

Please let me know if I handled anything incorrectly with removing the `gwenhywfar-gtk` subpackage. Nothing depends on it and it's GTK2, so it should be fine to remove.
