Before Commit:
Currently, when a user marks their answer as the best answer in the forum, an
error notification appears with the message 'Sorry, you cannot vote for your own
posts' However, this error message lacks clarity and does not clarify
the underlying issue.
After Commit:
Now the error message is modified to 'Sorry,
you cannot select your own posts as the best answer'
