Upgrade to TypeScript 4.7 and lock TS minor version

TS releases aren't completely backwards-compatible so locking on minor
version to make sure all upgrades are intentional.

Also update tsconfig options a bit. Module is now the stable 'ES2022'
value instead of 'esnext' which changes between TS versions. Target
and lib are now 'ES2021' since new-tab is only run on modern browsers.

Also bump Prettier version.
