[Data] Remove deprecated read_parquet_bulk API

[rushikeshadhav]

Description

This PR removes the deprecated read_parquet_bulk API from Ray Data, along with its implementation and documentation. This function was deprecated in favor of read_parquet, which now covers all equivalent use cases. The deprecation warning stated removal after May 2025, and that deadline has passed — so this cleanup reduces maintenance burden and prevents user confusion.

Summary of changes

• Removed read_parquet_bulk from read_api.py and init.py
• Deleted ParquetBulkDatasource + its file
• Removed related tests and documentation
• Updated references and docstrings mentioning the deprecated API

Fixes #58969

Code Review

This pull request effectively removes the deprecated read_parquet_bulk API, which helps reduce maintenance and prevent user confusion. The changes are comprehensive, covering the function's implementation, tests, documentation, and internal references. The code removal is clean and I only have one minor suggestion to improve the clarity of an updated docstring.

Bug: Orphaned parametrize decorators stacked on unrelated test function

The @pytest.mark.parametrize decorators for the deleted test_parquet_read_bulk and test_parquet_read_bulk_meta_provider functions were not removed along with the functions. These orphaned decorators (lines 234-249 and 250-265) are now stacked on top of test_parquet_read_partitioned, causing that test to have three parametrize decorators instead of one. This results in the test running with a Cartesian product of parameters from all three decorators, dramatically increasing test execution time and potentially causing failures from duplicate parameter name conflicts.
