bash: remove redundant out-of-band OSC 133;A (#10747)

The printf was part of the original script (9d6121245), and at the time,
this was the only place we'd emit the 133;A mark.

A PS1-based 133;P;k=i mark was introduced in 2bf1f80f7, and then it
become a full 133;A mark in aa47047a6, making the original printf line
redundant (because bash will also redraw PS1 on SIGWINCH).

The PS1-based 133;A was only missing the aid= option, and with that
added, it handles all of our cases (prompts, initial draw, and resizes).
