Label for LTS kernels

[dai5m5iq]

Kernels in the list of kernels come with labels of experimental, real-time or running. However, there is no label for kernels being LTS.

Describe the solution you'd like
Although obvious that all other kernels available in the list must be LTS, it might not be clear for beginner users which kernels are LTS. LTS kernels should have a Label also.

Additional remark
LTS label and Running label may interfere with each other.
