feat: enable vector API

[JBOClara]

What this PR does:
This PR introduces the ability to enable the Vector API within the telemetry configuration. A new ApiConfig struct is added to VectorSpec to handle the API's enablement. If enabled is set to true in the telemetry specification, the API configuration will be included in the generated Vector TOML configuration.

Functional Changes:

• Added an ApiConfig struct to the VectorSpec.
• The behavior to enable the API if the enabled property is set to true in the ApiConfig.

Technical Changes:

• Updates in telemetry_types.go to add the new ApiConfig.
• Modifications in vector.go to check the enabled property and configure the Vector TOML accordingly.
