[12.x] Fix spacing inconsistency before ellipsis in event comments

[AhmedAlaa4611]

Description

This PR fixes a minor formatting inconsistency in the Laravel Events docs. Specifically, it removes an extra space before the ellipsis (...)

This change aligns it with the formatting used in other comments throughout the codebase, where no space precedes the ellipsis.

Afaik, the rule of thumb is:

• If you truncate the word itself: no space
• If you truncate the sentence, but the last word isn't truncated: space
