Tested by:

1. pointing my fork https://github.com/jankeromnes/template-ruby-on-rails-postgres/blob/main/.gitpod.Dockerfile to gitpod/workspace-postgres:branch-jx-update-brew-1
2. opening the fork in Gitpod: https://gitpod.io/#https://github.com/jankeromnes/template-ruby-on-rails-postgres
3. confirming that brew update works fine

FYI, current production Gitpod seems to be on:

$ brew --version
Homebrew 3.2.9
Homebrew/homebrew-core (git revision e811be8b63d; last commit 2021-08-25)

While this updated image has this out-of-the-box:

$ brew --version
Homebrew 3.2.12
Homebrew/homebrew-core (git revision 32c831b13f9; last commit 2021-09-17)

Unfortunately, brew install stripe/stripe-cli/stripe is still broken today:

$ brew update
[...]

$ brew --version
Homebrew 3.2.12
Homebrew/homebrew-core (git revision 8a1f31f2b6f; last commit 2021-09-20)

$ brew install stripe/stripe-cli/stripe

This seems to be a bug in Stripe CLI's formula: stripe/stripe-cli#645
