runtime(netrw): Do not create swapfiles in netrw buffers
Problem: When using netrw to navigate directories, vim immediately
creates, then deletes a swap file in the entered directory,
causing the lastModifiedTime of that directory to change.
Solution: Use the :noswapfile command modifier in s:NetrwEditFile()
fixes: #18854
