great, this addresses part of #2263

Looks like there are some lint failures in the build @andy-ms

[nchen63]

are the changes to package.json needed?

I added a .d.ts file in a lint rule, which was being linted. Can't make it a .test.ts file, and that seems unnecessary if we can just ignore the entire directory.
EDIT: Looking at this more... actually I was getting confused because some files from #2273 were hanging around. (I had created a node_modules for the test imports, but looks like that isn't necessary.)
