Rename `batchInsert()` to `insertBatch()` with optional `$columns`

[Tigrov]

Mark batchInsert() as deprecated

db-migration/src/MigrationBuilder.php

Lines 119 to 124 in 38fdc07

	public function batchInsert(string $table, array $columns, iterable $rows): void
	{
	$time = $this->beginCommand("Insert into $table");
	$this->db->createCommand()->insertBatch($table, $rows, $columns)->execute();
	$this->endCommand($time);
	}

Add insertBatch() where $columns argument is optional:

public function insertBatch(string $table, iterable $rows, array $columns = []): void

BC could be kept if we leave the old method as a deprecated one.
