[PATCH] gitignore: add VSCode workspace dir

[Inochi Amaoto]

I agree with you that projects should be responsible for their own build
outputs. I know you want to keep the project clean, but it is not good
if the developers upload files associated with the editor by mistake.

Maybe we just ignore any file begin with dot and allow some exception (like
.clang-format and .gitignore itself). This way is already used in linux and
it works well.
AFAIK, the *.swp also begin with a dot, so this can also solve this issue.
