feature(connectors/bright_data_serp): add Bright Data SERP connector

[adomhamza]

Description of Change

`This is my first contribution to the Fivetran Connector SDK repository. It adds a Bright Data SERP connector that syncs search engine results from Bright Data's SERP REST API into a Fivetran destination.

The connector supports Google, Bing, and Yandex, accepts multiple search_query formats (single value, comma-separated, newline-separated, JSON array string), flattens nested JSON responses, and upserts rows to a search_results table keyed by query and result_index.

What's included

• connector.py — schema(), update(), checkpointing, and query parsing
• helpers/search.py — Bright Data API calls with retry/backoff
• helpers/data_processing.py — flattening, field discovery, and upsert logic
• helpers/validation.py — configuration validation
• README.md — connector documentation per the repo template
• configuration.json — placeholder values for required config fields

Design decisions (aligned with SDK guidelines)

• Primary keys and types declared in schema(); remaining columns inferred from data
• No fields.yaml / PyYAML — field discovery happens at runtime via collect_all_fields()
• No extra requirements.txt dependencies (uses pre-installed fivetran_connector_sdk and requests)
• Required connector log at start of update(): log.warning("Example: Connectors : Bright Data SERP")`

Testing

Checklist

Some tips and links to help validate your PR:

• Tested the connector with fivetran debug command.
• Added/Updated example-specific README.md file, see the README template for the required structure and guidelines.
• Followed Python Coding Standards, refer here
