fix(dependencies): update requirements and OCPP compatibility

[pabloariasmora]

• feat: specify exact package versions in requirements.txt per AWS MWAA best practices
• fix: restrict websockets to <14.0 due to OCPP v2.0.0 compatibility
• refactor: rename RegistrationStatusType to RegistrationStatusEnumType
• refactor: replace deprecated BootNotificationPayload with BootNotification
• refactor: replace deprecated HeartbeatPayload with Heartbeat()

*Issue #, #153

Description of changes:

I have identified and fixed the root cause of the WebSocket Error 1011. The issue stems from multiple compatibility and dependency management challenges:

1. OCPP Protocol Compatibility Issues:

• The websockets library versions >=14.0 introduce breaking changes that affect OCPP v2.0.0 implementations
• Recent versions of the OCPP library deprecated several payload types that we were using

2. Dependency Management Problems:

• Unpinned dependencies in requirements.txt leading to potentially incompatible package versions being installed
• Usage of deprecated OCPP payload types causing internal server errors during WebSocket handshake
• Misalignment between python requirements and loose dependency specifications
• The solution involves:

a) Package Version Management:

• Implemented strict version pinning following AWS best practices
• Specifically restricted websockets==13.0 to maintain OCPP compatibility
• Updated some dependencies to their last known compatible versions

b) OCPP Implementation Updates:

• Replaced RegistrationStatusType with RegistrationStatusEnumType
• Updated BootNotificationPayload to BootNotification
• Migrated from HeartbeatPayload to Heartbeat
• Ensured all OCPP message types align with current specifications

c) Code Modernization:

• Removed deprecated API calls
• Updated payload structures to match current OCPP standards

could you just pin the version on the other packages in cpp-gateway-container/requirements.txt for consistency and best practice
