Fix #114867: 'i' key in Turkish layout is marked as 'EVT_QUOTEKEY'

Different from most layouts. The Turkish keyboard layout treats the `i` as the lowercase `İ` and the `ı` as the lowercase `I`.

So we have 2 different types of i: `ı` and `İ`. And two different I key positions on the keyboard.

This key with a different position is mapped as special and returns the corresponding `event->type` of the US keyboard `"` (`EVT_QUOTEKEY`).

The apparently most appropriate event for this key would be `EVT_IKEY`.

This type of change needs to be treated with care, as it may alter other shortcuts that are already common to Turkish users.
