Docs: Jupyter Configuration link is broken

[wydsith]

Flagged by Richard on slack

Jupyter Configuration link at the bottom of this page https://docs.posit.co/rsconnect-jupyter/#posit-workbench is incorrect

it should be:
https://docs.posit.co/ide/server-pro/jupyter_sessions/configuration.html

There's also a number of style guide errors on the page that could use cleanup
