Support to execute reticulate input

[dfalbel]

This will help addressing #3865
Also helps with: #6541

Previously, the reticulate extension would just ignore the code passed using the input argument of reticulate::real_python(). Turns out that's what is currently used by the quarto extension to send code to the reticulate repl. We now make sure that it's executed in the reticulate console.

Needs: posit-dev/ark#730

Release Notes

New Features

• N/A

Bug Fixes

• Reticulate no longer ignores the input argument of repl_python() (Improve behavior of reticulate Quarto documents (R & Python together) #3865)

QA Notes

This can be tested by running:

reticulate::repl_python(input="x= 1")

This could should be executed in the Reticulate Python console.
