Config backup via new api endpoint (#51)

[jan-win1993]

• Added new command "configbackup" which uses the newer API-endpoint (in OPNsense core) to download config bacup
• Did not modify the old "apibackup" command
• Added remarks to the help pages of the "apibackup" and "configbackup" commands

[jan-win1993]

With the release of OPNsense version 24.1 the plugin "os-api-backup" was discontinued and therefore the old API-endpoint for configuration backups can't be used anymore.
I've added a new command "configbackup" which uses the newer API-endpoint (which resides in the OPNsense core library) to download the configuration backup.
To ensure backwards compatibility I did not modify the old "apibackup" command and added some remarks to the help pages of the "apibackup" and "configbackup" commands.
The unit test did run successfully in isolation:

opnsense_cli/tests/commands/core/test_configbackup.py::TestApibackupCommands::test_download PASSED  [100%]                                    

Best regards,
Jan.
