Upgrade: material_file_input

[pablo-rodr-bio2]

It would be great if material_file_input() also had an "accept" argument like shiny::fileInput(), "A character vector of "unique file type specifiers" which gives the browser a hint as to the type of file the server expects. Many browsers use this prevent the user from selecting an invalid file"

Hello, I tried to use 'accept', but it did not exist

material_file_input('file', label = "Upload file", accept = '.h5')
