introduce decorators for tm_g_scatterplot

[m7pr]

Part of #863

Working Example

pkgload::load_all("../teal")
pkgload::load_all(".")

footnote_dec <- teal_transform_module(
  label = "Footnote",
  ui = function(id) shiny::textInput(shiny::NS(id, "footnote"), "Footnote", value = "I am a good decorator"),
  server = function(id, data) {
    moduleServer(id, function(input, output, session) {
      logger::log_info("🟢 Footnote called to action!", namespace = "teal.modules.general")
      reactive(
        within(
          data(),
          {
            footnote_str <- footnote
            plot <- plot + ggplot2::labs(caption = footnote_str)
          },
          footnote = input$footnote
        )
      )
    })
  }
)

Hey @averissimo on brushing, this module also displays data table.
Do you thin we should allow to decorate this datatable as well?

[averissimo]

@m7pr does the table appear in code? if not then I don't think so

[m7pr]

@averissimo the code for the table was never intended to be added to the Show R Code so I guess table is just a nice to have. Will omit table for this PR.
