convert-to-single-host failed with "Error modifying for single host: ENOENT: no such file or directory, unlink 'CONTRIBUTING.md'"

After the Dev Kit released. We're checking the telemetry of "create new add-in" event and found this bug.

Below is the logic in Dev Kit. Basically it's the same as yo office, which download the templates and unzip it, and then run npm run convert-to-single-host --if-present -- ${officeHostApp.toLowerCase()}

We got 7 failures out of 102 total creation with error log like this.

Seems like the "CONTRIBUTING.md" file is missing in certain repo. I don't know which specific template it comes from, so I just create a bug here. I will try to find which template caused these bugs.

This error exists in sso js/ts repo. Will close this issue open new one in the right repo.
