Speed up pre-push hook

[gtrufitt]

What does this change?

• Jest only runs on changed files
• Eslint only runs on staged files
• We don't check bundling

TSC still runs on everything, maybe opportunities there.

Before and after is with no changes to files so it will be slower, but still much quicker.

Before

After

Update After

Ok, so added parallelisation with https://github.com/mysticatea/npm-run-all/blob/HEAD/docs/run-p.md

Why?

Pre push is valuable, but 2 minutes is a long time.
