[Feature Request]: Extend Show R code with an information about the reproducibility features

[m7pr]

A follow-up after introduction of the lockfile in here #1232
Idea started in here

So far the whole reproducibility info was displayed in the modal with the module reproducibility code. Would it be good to introduce a small text in there: "Run this code on restored env from lock file available [here]". Something like that pointing to the link to that lockfile.

Alternatively, we could introduce a button "Download bundle" which will generate a directory (packed in zip) containing:

• renv
• .Rprofile
• .Renviron
• script.R

Opening such directory should allow script.R execution.

Yes, all the options() set in .Rprofile. All the Sys.env() packed in .Renvrion. renv::activate() packed in .Rprofile
