chore: widen the build triggers and pin set

A pack is the platform baseline plus what its cores need, so a profile
change alters pack contents; build.yml did not watch emulators/. Its
release notes read git log -15 on a depth-1 clone, which returns one
commit, and its test step ran a single module out of nineteen.

validate.yml ignored install.sh and install.ps1, so a PR touching only
a bootstrap skipped the test that pins them to install.py.

checkout and setup-python were pinned to v6 in two workflows and v7 in
the others; jsonschema was imported by validate_schemas.py and
declared nowhere, and requires-python claimed 3.10 while both
bootstraps accept 3.8.
