deprecated gather_()` function from tidyr

[AbdurrahmanMN]

When running this in R
visdat::vis_miss(airquality) %>% plotly::ggplotly()
I had this output

Warning message:

i Please use `gather()` instead.
i The deprecated feature was likely used in the visdat package.

Hi there,

Thanks for this, this has been resolved in the development branch of visdat, which should be submitted to CRAN soon :)
