pnpm exec outputs garbage before running command if .pnpmfile.cjs exists

[anomiex]

Since 7.5.1, pnpm now outputs some garbage before running the command. This breaks things if the output is being piped into another process.

pnpm version: 7.5.1

Code to reproduce the issue:

Create an empty directory. Run the following:

1. pnpm add hello-world-npm
2. echo 'module.exports = {}' > .pnpmfile.cjs
3. pnpm hello-world-npm

Expected behavior:

Output is

Hello World NPM

Actual behavior:

Output is

Using hooks from: /tmp/test/.pnpmfile.cjs
Hello World NPM

Additional information:

• node -v prints: v16.16.0
• Windows, macOS, or Linux?: Linux

Looks like this was a side effect of #5012, output that formerly went to the log file now goes to the console.

This is the same issue as actions/setup-node#543
