refactor: update and simplify some dependencies

[dpogue]

Motivation and Context

Since we can't adopt the latest versions of execa and globby due to ESM, and we use them for very specific purposes here, replace them with built-ins where possible (and use fast-glob where not possible).

Description

• Replace the single execa call with child_process.spawnSync, since we know that we're invoking git rather than a shell script
• Replace the one spot that used globby with fast-glob
• On versions of node with fs.globSync, use that instead of fast-glob
• Fix a warning in a Jasmine test about done getting called with arguments
• Update testing dependencies to latest versions

Testing

• Confirmed that the contents of the cordova.js file are the same before and after these changes (some extra spaces removed, but no code changes)
• Confirmed that all unit tests run and pass

Checklist

• I've run the tests to see all new and existing tests pass
