Correct elife for `cs2_wo_timecorr`

[dachengx]

What does the code in this PR do / what does it improve?

In https://github.com/XENONnT/straxen/pull/1258, the elife correction of cs2_wo_timecorr in corrected_areas was removed. To be aligned with PeakCorrectedAreas https://github.com/XENONnT/straxen/blob/7e49677eead6e88d9dffb12e6f6d457a67daeb6b/straxen/plugins/peaks/peak_corrections.py#L10, we should correct the elife also for cs2_wo_timecorr.

Can you briefly describe how it works?

Can you give a minimal working example (or illustrate with a figure)?
