[docs] Glossary mistake

[Gaston Fiore]

Hello,

In the glossary, in the definition of "file object", there's an extra
word "other" in the second sentence of the definition. It currently
reads:

"Depending on the way it was created, a file object can mediate access
to a real on-disk file or to another other type of storage or
communication device (for example standard input/output, in-memory
buffers, sockets, pipes, etc.)."

It should instead read:

"Depending on the way it was created, a file object can mediate access
to a real on-disk file or to another type of storage or communication
device (for example standard input/output, in-memory buffers, sockets,
pipes, etc.)."

Best,

-Gaston
