update check-style setting for LY corp copyright

[taisey]

Motivation:
In the latest developer guide, it is recommended to use Copyright $today.year LY Corporation, but the check-style settings have not been adapted accordingly. When this copyright notice is used, a check-style warning occurs.
Modifications:

• Updated check-style setting for LY corp copyright

Result:

• Using either LINE copyright or LY copyright will pass the check-style test.
