This commit addresses two main issues:
The 'b2_enabled' value was not being stored in the config JSON. Added it to the config JSON to enable or disable B2 bucket uploads as needed.
Corrected the execution of b2-cli commands in the MysqlDatabaseBackup class using backticks for proper shell command execution in Ruby.
These changes should resolve the issue of the database dump file not being uploaded to the B2 bucket.
