xterm@5.2.0-beta.21

fix #172222

@meganrogge -- Yep, this resolves the regression. Did the readonly introduce the inadvertent regression? Now deletion key works again in the buffer.

FYI, aria-live works nicely; however, line-by-line navigation mode via Ctrl+UpArrow/DownArrow keeps saying 1 of 21, 10 of 21, etc. without any actual content being read.

@jooyoungseo the regression was in removing a line which inserted the .xterm-accessibility element into the dom 😅 when we added the .xterm-accessibility-buffer

From @Tyriar: Readonly was causing up/down to scroll instead of move a cursor around. This is probably up to the browser, but we want this to also work for non-screen reader users for keyboard accessible selection.

Re navigation mode, ok we will look into that - as we've said, we're hoping this new accessible buffer can replace the need for that

With readonly unfortunately Electron surprisingly didn't use a cursor, we want this for non-screen reader users for keyboard selection support as well.
