Referring to quantities in documentation should use commas

[vjeetje]

On https://google.aip.dev/132 we have this documentation:

  // The maximum number of books to return. The service may return fewer than
  // this value.
  // If unspecified, at most 50 books will be returned.
  // The maximum value is 1000; values above 1000 will be coerced to 1000.
  int32 page_size = 2;

The standard in American English is to separate 1000s by a comma. Suggestion is to replace these types of documentation with:

  // The maximum number of books to return. The service may return fewer than
  // this value.
  // If unspecified, at most 50 books will be returned.
  // The maximum value is 1,000; values above 1,000 will be coerced to 1,000.
  int32 page_size = 2;
