fix: update deploy-docs workflow to use v1.7.3

Use specific version v1.7.3 instead of major version v1 to restore
missing functionality (target-directory, commit-message, user-name).

The v1 major tag points to a different, simplified version that lacks
the features our workflow requires. v1.7.3 maintains full compatibility
with our existing configuration while providing Node.js 24 support.
