[DOCS]: Provide color on the transaction attribute in FindOneOptions / SaveOptions

[luizguilhermefr]

What was unclear or otherwise insufficient?

In the documentation, there are no mentions at all of the transaction boolean flag that is present on the FindOneOptions and SaveOptions interfaces.

typeorm/src/find-options/FindOneOptions.ts

Lines 109 to 113 in 6c928a4

	/**
	* If this is set to true, SELECT query in a `find` method will be executed in a transaction.
	*/
	transaction?: boolean

typeorm/src/repository/SaveOptions.ts

Lines 17 to 21 in 6c928a4

	/**
	* By default transactions are enabled and all queries in persistence operation are wrapped into the transaction.
	* You can disable this behaviour by setting { transaction: false } in the persistence options.
	*/
	transaction?: boolean

I am confused if when I am using a data source transaction, I should use it within my statements or not.

Recommended Fix

Documentation I'd expect to have more color about those flags: https://typeorm.io/transactions
