Use exact Ruby version 3.3.7 in Pro workflows

The Pro package Gemfile specifies exact version 'ruby 3.3.7', but using
ruby-version: 3.3 in GitHub Actions installs the latest 3.3.x (3.3.9),
causing a version mismatch error.

Changed all Pro workflows to use exact version 3.3.7:
- pro-lint.yml: 3.3 → 3.3.7
- pro-package-tests.yml: ['3.3'] → ['3.3.7']
- pro-integration-tests.yml: 3.3 → 3.3.7 (all jobs)

This fixes: 'Your Ruby version is 3.3.9, but your Gemfile specified 3.3.7'
