[v1] watchdog: fix typo in the comment

Commit Message

Yan Zhen Sept. 23, 2024, 7:50 a.m. UTC

Correctly spelled comments make it easier for the reader to understand
the code.

Fix typos:
'hearbeat' -> 'heartbeat',
'retrigggers' -> 'retriggers',
'funtions' -> 'functions',
'Resgister' -> 'Register'.
