Steps to reproduce

2. git config --global user.signingkey <your key>
3. vue create my-project
4. cancel GPG sign

What is expected?

Warning stating that git commit failed due to failed GPG signing

What is actually happening?

Warning stating that failure was due to missing username and email

The simplest fix might be to just change the warning from Skipped git commit due to missing username and email in git config to just Could not create initial commit.

Or you could pass the --no-gpg-sign flag when running git commit to prevent git from attempting to sign a commit created by vue-cli.
