Update dependency probot to v6

[renovate]

This Pull Request updates dependency probot from v5.0.1 to v6.0.0

Release Notes

v6.0.0

Breaking Changes

• Migrate to @​octokit/rest.js, which is the latest version of the node-github client. There shouldn't be any noticeable changes, but since @octokit/rest is a complete rewrite of the node-github internals, we're marking this a breaking change just to be safe. (#​400)

Improvements

• Allow setting name on logger components. (#​355)

  robot.on('issues.opened', context => {
    const log = context.log.child({name: 'my-issue-thingy'});
  });

Community
