C++ could not be hidden in Top Langs

[swapnanildutta]

Describe the bug
When I wanted to hide the C++ from Top Langs, it just didn't work. Instead, it hid the C language bar.

Expected behavior
I expected to type hide=c++ in the top langs API and it would hide the c++ bar. I even tried using cpp if that was valid but didn't work.

Screenshots / Live demo link (paste the github-readme-stats link as markdown image)
The api calling

The result, left one is earlier top langs card, right one after hiding c++

Additional context
Add any other context about the problem here.

The plus symbol "+" in "c++" is URI reserved character, as specified in Wikipedia
You should use "c%2B%2B" instead of "c++" like this:

Demo:

For your record, if you want to hide "Jupyter Notebook", you should use "jupyter%20notebook" instead:
