upgrade prompt-toolit to 3.0 (#1149)

* upgrade prompt-toolit to 3.0

fix: https://github.com/dbcli/pgcli/issues/1148

related:
https://github.com/prompt-toolkit/python-prompt-toolkit/issues/886

in order to make the `behave` test pass, I have to:

- extend timeout for database connection test.
- extend timeout for basic command expect.
- extend timeout for features/steps/crud_table.py:: see data selected.
- disable cpr for features but "run the cli"

* [ci] disable CPR for all behave tests.

* bugfix: remove duplicated prompt expect.

* [ci] delete CPR env setting.

* Revert "[ci] delete CPR env setting."

This reverts commit fe4d5b565e.

* revert the extending timeout back.

* [ci] test when didn't disable CPR.

* Revert "[ci] test when didn't disable CPR."

This reverts commit d379b1e736.
