[WITHDRAW] Documentation: Fix duplicated words - "in in" was not an error

[Wang Zihan]

From: Wang Zihan <3772548978 at qq.com>

I apologize for another incorrect patch. After review by Björn Persson,
I realized that "in in" in switchdev.rst was not an error:

Original: "what position a port is in in the overall topology"

This is correct English:
- "what position a port is in" = the position that a port occupies
- "in the overall topology" = within the overall topology

My change incorrectly altered the meaning to suggest that a port IS a position,
when in fact a port is IN a position IN the topology.

I am withdrawing the "in in" part of this patch:
- Message-ID: <20260502111916.145238-1-3772548978 at qq.com>

The other parts ("The the" -> "The" and "on on" -> "on") were also incorrect
as previously acknowledged.

Thank you for the correction. I will be more careful in analyzing English
grammar before submitting patches.

Apologies for the noise.

Wang Zihan
