* build: set exact version of Prettier in lockfile

The reason:

From https://prettier.io/blog/2021/05/09/2.3.0.html

> And just a reminder, when Prettier is installed or updated, it’s
> strongly recommended to specify the exact version in package.json:
> "2.3.0", not "^2.3.0".

From https://prettier.io/docs/en/install.html#summary

> Install an exact version of Prettier locally in your project. This
> makes sure that everyone in the project gets the exact same version of
> Prettier. Even a patch release of Prettier can result in slightly
> different formatting, so you wouldn’t want different team members
> using different versions and formatting each other’s changes back and
> forth.
