Prevent line numbers from being copied in search results

[ipagbox]

What kind of change does this PR introduce? (check at least one)

• Bugfix
• Feature
• Code style update
• Refactor
• Build-related changes
• Other, please describe:

The PR fulfills these requirements:

• All tests are passing?
• New/updated tests are included?
• If any static assets have been updated, has ui/bindata.go been regenerated?
• Are there doc blocks for functions that I updated/created?

If adding a new feature, the PR's description includes:

• A convincing reason for adding this feature (to avoid wasting your time, it's best to open a suggestion issue first and wait for approval before working on it)

Other information:
When I want to copy multiple lines of code from the search results, the line numbers are also copied.

So when I paste this into IDE or console, it may cause syntax errors.

The solution is to prevent line numbers from being copied in search results using CSS.

I hope this little trick is helpful.

P.S. As I noticed, now there is no need to regenerateui/bindata.go. So this line may be deleted from PR template. Right?

Thank you for the nudge @ipagbox. Lemme send this around to the rest of the team to see what they think, but this looks more than fine to me.
