build: update to husky@6

* build: update to husky@6

Upgrade husky from 5.2.0 to 6.0.0

* build: install husky in `prepare` script instead of `postinstall`

With typicode/husky#890, the recommended way to install husky is in the
`prepare` script instead of the `postinstall`. This commit moves
the husky installation to the `prepare` script to align with the new
recommendation.
