chore(ci): Add code scanning & fix dependabot failures

[dpogue]

Platforms affected

all

Motivation and Context

Improve CI.

Description

• Fix errors when dependabot PRs try to run tests in CI
• Add JavaScript code scanning with CodeQL

CodeQL doesn't support Objective C, and I tried enabling the Swift scanning but it caused everything to run so slowly that all the tests timed out. But we don't actually have much Swift code, do I doubt that it worth trying to enable that right now.

Testing

• Ran in CI, tests pass

Checklist

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