fix: bext gitlab hover-overlay issue
Created by: abeatrix
Summary
Close https://github.com/sourcegraph/sourcegraph/issues/35315
User has reported that the hover overlay is hidden by other elements when checking out diff on GitLab.
It looks like it is because a smaller z-index (100) from the general hover module overtook the one that is supposed to work in the code host (2000)
Setting the z-index for the code host overlay module as !important has resolved the issue.
Before
Using z-index of 100 instead of 2000
After
Using z-index of 2000 instead of 100
Test plan
Manually tested
