[pgk/ottl] Remove debug log from invalidComparison (#31813)

**Description:**
When we added the boolean comparison feature we included a debug log to
help troubleshoot when 2 comparisons were invalid, such as checking if a
`string` was equal to a `float64`. Since then we've had complaints about
how noisy the log is, mainly because it happens when checking against
`nil`, which happens frequently when checking if an attribute has a
specific value when it is present.

This PR removes the log.
