fix(rivetkit): pack inspector in pkg-pr-new

[NathanFlurry]

Description

Align the pkg-pr-new workflow with the release pipeline for RivetKit inspector packaging.
The workflow now builds publishable RivetKit packages with the release exclusions and then runs build:pack-inspector explicitly so the real inspector frontend is bundled before preview publishing.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

Compared the workflow steps against the release scripts and reviewed the resulting PR diff.
Ran npx turbo run build:pack-inspector -F rivetkit --dry=json to confirm the pack step still depends on @rivetkit/engine-frontend#build:inspector.
Did not run the full build or publish pipeline.
