Fix deploying the TS migration dashboard

[mcmire]

Explanation

When the TypeScript migration dashboard is updated, it is built and deployed in another repo, which is then deployed via GitHub Pages. To push to this repo we have to set a Git username and email. This is missing from the CircleCI config, so this commit uses the metamaskbot GitHub account to do that.

More Information

See the PR introducing the TypeScript migration dashboard for more context.

Also see Storybook, which takes a similar approach.

Manual Testing Steps

There isn't anything to test here, but the job-publish-ts-migration-dashboard step in CircleCI should not fail. This step will only get run when this PR is merged, so a subsequent PR will be needed if this one doesn't fix it.
