fix: do not escape newlines

📚 Description

Currently newlines are escaped when putting strings as fields into @nuxt/content. That means that the newlines that are returned from e.g. queryCollection aren't real newlines but slashes followed by an n char. This is clearly visible when converting the field value to JSON, then the output looks something like line1\\nline2 instead of line1\nline2. Concretely this breaks my nuxt-content-body-html module that generates a html for @nuxt/content posts. In the final result e.g. in code blocks, there will just be \n strings instead of real line breaks.

I think there are two issues:

1. The newlines are escaped when generating the inserts
2. Actual newlines are used to split the decompressed dump on client side

I've fixed them by keeping the newlines in the queries and using JSON.stringify and JSON.parse to communicate the dump between server and client instead of spliting by \n.

I haven't fixed the tests yet since I don't know yet if the PR gets merged.
