fix(tui): correct CSI sequence (#17844)

Browse Source 
Follow up to #17771. The sequence `CSI > 4 ; 1 m` does not enable
distinguishing all available keys; notably, it excludes `<Tab>`. Using
`CSI > 4 ; 2 m` tells the terminal to disambiguate *all* keys, which is
much more useful.

The meaning of the final parameter is documented [here][1].
