docs: update Textract docs (#31992)

I am modifying two things:

1. "This sample demonstrates" with "The following samples demonstrate"
as we're talking about at least 4 samples
2. Bringing the sentence to after talking about the definition of
textract to keep the document organized (textract definition then
samples)

Today, many companies manually extract data from scanned documents such as PDFs, images, tables, and forms, or through simple OCR software that requires manual configuration (which often must be updated when the form changes). To overcome these manual and expensive processes, `Textract` uses ML to read and process any type of document, accurately extracting text, handwriting, tables, and other data with no manual effort. \n",
