Subject: [PATCH] vimUtils.buildVimPlugin: fix helptag generation (#53071)

I messed that up in my refactoring in #52767, since I moved the relevant
bash code out of a function and failed to adjust the shell variable
name. Now the plugin build will fail loudly when help tag generation
fails to make sure this doesn't happen again.
