chore: Remove odd import (#6769)

#### Details

The reports package contains an odd import that seems out of place
because:
- It imports from the `playwright` package, which isn't a product
dependency
- The imported variable of `_electron` is never used by the code
- Tests all pass when the import is removed

##### Motivation

Code hygiene

##### Context

I came across this during the Android deprecation. I searched for
"electron" and this was the list remaining instance in the code. I kept
it out of the Android cleanup PR since it wasn't directly connected. The
line was added in #5048, where it seems to have slipped in accidentally.

<!-- Are there any parts that you've intentionally left out-of-scope for
a later PR to handle? -->

<!-- Were there any alternative approaches you considered? What
tradeoffs did you consider? -->
