Support find-replace

Is your feature request related to a problem? Please describe.
It would be nice to use telescope as a one stop shop for both finding and replacing content in files.

Describe the solution you'd like
rg has the --replace flag which allows replacing the match, a key binding which would then perform the actual replacement is needed as a final step.

Additional context

wow, did't know that before.
Adding a short cut to add --replace is quite simple, but how to render the diff preview of origin/replace?
Is there any idea?

Interesting idea 🤔

Unfortunately ripgrep doesn't support replace. From the man page

-r REPLACEMENT, --replace=REPLACEMENT
           Replaces every match with the text given when printing results. Neither this flag nor any other ripgrep flag will modify your files.
