What if add our username to the front of the solution file?

[Leslie-Wong-H]

Now the author of vscode-leetcode has divided the original solution file into two part, one to store the user's solution, and the other to preview the problem description after 0.13.0.

I notice there are several formated symbols in the front of all solution files, like

#
# @lc app=leetcode id=40 lang=python3
#
# [40] Combination Sum II
#

Therefore, my proposal is, how about adding our usernames here automatically? as a sign for copyright~~

For example,

#
# @lc app=leetcode id=40 lang=python3
#
# [40] Combination Sum II
#
# @Leslie_Wong
