feat: significantly reduce payload install size by removing unnecessary monaco-editor dependency (#7939)

This reduces the total install size of `payload` from 115 MB to 34 MB. 

We never used monaco-editor within payload - we were only using
`@monaco-editor/react` which is a lot smaller.

Since we expose its types to the end user, we have to add it to our
`dependencies`, not `devDependencies`.

Before:
https://npmgraph.js.org/[email protected]#select=exact%3Apayload%403.0.0-canary.1a675ae&zoom=w

After:
https://npmgraph.js.org/?q=payload%403.0.0-canary.cdb9474#zoom=h&select=exact%3Apayload%403.0.0-canary.cdb9474
