Feature Request

Given I install TCE with homebrew using brew install vmware-tanzu/tanzu/tanzu-community-edition
When I run brew info vmware-tanzu/tanzu/tanzu-community-edition
Then I should see the same output I see after installation:

==> Thanks for installing Tanzu Community Edition!
==> The Tanzu CLI has been installed on your system
==>

Looks like we also need to update the version in that path to be dynamic
