Description

According to SAMD2xG datasheet, D26 line, PA27 is connected to EXTINT[15].
This is not indicated in the table in the variants.cpp

https://github.com/arduino/ArduinoCore-samd/blob/993398cb7a23a4e0f821a73501ae98053773165b/variants/arduino_zero/variant.cpp#L68

Saved my project since I needed all 16 interrupts and other lines are used for other things.
I've moved the Tx LED to another line that can't be used as an interrupt.

Can someone please update the file?
Don't want to create a repo for such a small change...

Research direction

Open variants/arduino_zero/variant.cpp around line 68 and compare the pin table with the SAMD2xG datasheet. Verify the D26/PA27 mapping to EXTINT[15], then confirm the table records it correctly; the issue is done when the mapping is represented there.
