feat: add the code for rsconnect instead of asking people to click on the button

[ColinFay]

In 03_deploy, there should be a piece of code for deployment with rsconnect

[yogat3ch]

Something like this?

rsconnect::deployApp(
  appName = desc::desc_get_field("Package"),
  appTitle = desc::desc_get_field("Package"),
  appFiles = c(
    "R/",
    "inst/",
    "data/",
    "NAMESPACE",
    "DESCRIPTION",
    "app.R",
    ".Rprofile",
    ".Renviron"
  ),
  appId = rsconnect::deployments(".")$appID,
  lint = FALSE,
  forceUpdate = TRUE
)

Yes indeed :)

Would you be willing to do a PR?
