B2KP-367 J-Link Flashing Issue Fix (hopefully) +semver:patch (#34)

Update the J-Link software tools version. This seems to fix the failures to flash. They mention it in their release notes but the use case isn't _obviously_ the same as ours:

>NXP S32K3xx: In multi-core setups with multiple sessions to different cores involved, flash programming could fail with "Failed to preserve target RAM @ 0x20000000-0x20007FFF" error. Fixed.
