fix: change log rotation format to pgcli.YYYY-MM-DD.log

Changed the log file rotation format from pgcli.log.YYYY-MM-DD
to pgcli.YYYY-MM-DD.log for better file naming conventions.

Changes:
- pgcli/main.py: Updated suffix format and added logic to strip .log extension
- pgcli/pgclirc: Updated documentation to reflect new format
