fix(icons): fix the naming for secure-lock-light

[Teamop]

Description

After adding in the https://github.com/momentum-design/momentum-ui/pull/1330, found that in order to use in CH, should still follow the naming convension for size suffix.

just got misleading by this commit - https://github.com/momentum-design/momentum-ui/commit/1b0023310376e84cac85f261932078e9936b6976, after trying to use in CH, still need the old naming pattern.
