An editor connected to a file get a title like 'abc.py - path/to/abc.py (3.11.0)'. (But see#65787.) The Shell starts with 'IDLE Shell 3.11.0' and if saved, adds pathand duplicate version. Instead, start with "IDLE Shell - (3.11.0) and insert path if saved.

Default file type is currently .py. I think it should be .txt unless and until add Save Code is added.

Could consider similar with new file. Grep title probably OK. Also note#3701 (unsaved indicator).
