ruby-build: definition not found: 2.7.1

Ruby 2.7.1 has been released, but I can not install it with rbenv.

I am on macOS 10.15.3 with ZSH and Homebrew.

❯ brew upgrade rbenv ruby-build
Warning: rbenv 1.1.2 already installed
Warning: ruby-build 20200224 already installed
❯ rbenv install 2.7.1
ruby-build: definition not found: 2.7.1

See all available versions with `rbenv install --list'.

If the version you need is missing, try upgrading ruby-build:

  brew update && brew upgrade ruby-build

Homebrew got a new upgrade for ruby-build which solved the problem.
