- Adds missing types, especially the `Where` type. Will be helpful for
people to see that they can type their queries like that
- Mention pnpm first and prefer pnpm > npm > yarn throughout docs
- Add `payload` to function arguments in examples to discourage people
from doing `import payload from 'payload'`
- PNPM => pnpm, NPM => npm
- Fix some typos
Example:
```sh
pnpm add @payloadcms/plugin-sentry
```
to:
```sh
pnpm add @payloadcms/plugin-sentry@beta
```
Because of this, people can be confused with the wrong installed
version. We'll change it back on stable
