git remote URL regexp is too restrictive

[pmdartus]

Observation

This bug is a follow-up from #184. After following the getting started steps and set up the git, the best CLI was still complaining about the following error:

Error: Unable to parse git repo
    at getRepository (/Users/p.dartus/code/github/pmdartus/benchmark-ci-test/node_modules/@best/config/build/utils/git.js:25:15)
    at process._tickCallback (internal/process/next_tick.js:68:7)

The issue is originated from the git remote URI parsing which is not permissive enough.
https://github.com/salesforce/best/blob/master/packages/@best/config/src/utils/git.ts#L29

The regexp only accepts user name and repository names with alphabetic characters, while my repository name contains a dash.
