[PATCH net v2] docs: tproxy: fix code block style

[Levi Zim via B4 Relay <devnull+rsworktech.outlook.com@kernel.org>]

From: Levi Zim <rsworktech@outlook.com>

The last command is not indented thus does not show as code block when
rendered. This patch fixes it.

Fixes: 4ac0b122ee63 ("docs: networking: convert tproxy.txt to ReST")
Signed-off-by: Levi Zim <rsworktech@outlook.com>

Changes in v2:
- Add double colons to the end of paragraph before the code block
- Link to v1: https://lore.kernel.org/r/20250427-tproxy-docs-fix-v1-1-988e94844ccb@outlook.com

 Note that for this to work you'll have to modify the proxy to enable (SOL_IP,
 IP_TRANSPARENT) for the listening socket.
