Remove trailing slash in osa submodule

Gerrit is not properly updating doc repo when we merge patches
in osa repo.

My current theory is that gerrit cannot properly match
a submodule to gerrit project as in .gitmodules project name is
written with trailing slash. As it's the only submodule that has this
trailing slash let's give it a try and remove that slash.
