Document datasette.urls.row and row_blob

[eyeseast]

These are in the codebase but not in documentation. I think everything else in this class is documented.

class Urls:
    ...
    def row(self, database, table, row_path, format=None):
        path = f"{self.table(database, table)}/{row_path}"
        if format is not None:
            path = path_with_format(path=path, format=format)
        return PrefixedUrlString(path)

    def row_blob(self, database, table, row_path, column):
        return self.table(database, table) + "/{}.blob?_blob_column={}".format(
            row_path, urllib.parse.quote_plus(column)
        )

Related issue - I'm not 100% settled on the design for these yet:

• Documentation and unit tests for urls.row() urls.row_blob() methods #1048 (comment)

Totally missed that issue. I can close this as a duplicate.
