Unnecessary `>` in README

I apologize for the small point, but I noticed that there is an unnecessary > at the end of the email in the following line in README.md.

create-github-app-token/README.md

Line 114 in 25cc3bd

git config --global user.email '${{ steps.get-user-id.outputs.user-id }}+${{ steps.app-token.outputs.app-slug }}[bot]@users.noreply.github.com>'

This is fixed in #186
