README links to command source code result in 404

[shazron]

Describe the bug
oclif/dev-cli has a bug where it assumes a version tag is prefixed by v when it should respect the setting in .npmrc. See oclif/dev-cli#123

Workaround is setting this key in the plugin's package.json:

"oclif": {
    "repositoryPrefix": "<%- repo %>/blob/<%- version %>/<%- commandPath %>"
  }

To Reproduce
See the section for a command in README.md, the link to the source goes to 404.

Expected behavior
The link works.

Actual behavior
The link does not work.
