Better detection for Enso's NI when launching LS

Previosly we were wrongly relying on the presence of the file. That way,
a bash script meant that NI integration was wrongly used.
This change uses Tika, but it has already been present in other
subprojects so no additional dependency shall be added.

Follow up on #11880.
