Reproduction steps

1. brew install pnpm
2. pnpm self-update
3. output: updating from version 12.8.1 to 12.8.1
4. I tried a second time to give a replication but it doesn't happen

Describe the Bug

brew pnpm installation allows self-update even if latest version is installed and it downloads the native binary (on Mac OS) maybe because of a folder mismatch since it only happens the first time
