### Issue Description

`>` characters were unexpectedly inserted into https://ubuntu.com/server/docs/how-to/debugging/debug-symbol-packages/#create-a-ddebs-list-file :

```text
$
echo "Types: deb
> URIs: http://ddebs.ubuntu.com/
> Suites: $(lsb_release -cs) $(lsb_release -cs)-updates $(lsb_release -cs)-proposed
> Components: main restricted universe multiverse
> Signed-by: /usr/share/keyrings/ubuntu-dbgsym-keyring.gpg" | \
> sudo tee -a /etc/apt/sources.list.d/ddebs.sources
```

Something inserted them, as the original https://github.com/canonical/ubuntu-server-documentation/blob/b9d3b55199196d56c2ca58ab033a6361dccef4b6/docs/how-to/debugging/debug-symbol-packages.md#L48-L53 doesn't have them.

This caused apt to fail, and required manually removing `>` from `/etc/apt/sources.list.d/ddebs.sources` and deleting `/etc/apt/sources.list.d/sudo`:

```console
root@daniel-desktop3:/etc/apt/sources.list.d# echo "Types: deb
> URIs: http://ddebs.ubuntu.com/
> Suites: $(lsb_release -cs) $(lsb_release -cs)-updates $(lsb_release -cs)-proposed
> Components: main restricted universe multiverse
> Signed-by: /usr/share/keyrings/ubuntu-dbgsym-keyring.gpg" | \
> sudo tee -a /etc/apt/sources.list.d/ddebs.sources
root@daniel-desktop3:/etc/apt/sources.list.d# apt update
Notice: Ignoring file 'sudo' in directory '/etc/apt/sources.list.d/' as it has no filename extension
Error: Malformed entry 1 in sources file /etc/apt/sources.list.d/ddebs.sources (URI)
Error: The list of sources could not be read.
root@daniel-desktop3:/etc/apt/sources.list.d# vim ddebs.sources
```

Start with docs/how-to/debugging/debug-symbol-packages.md at the referenced lines 48–53 and compare its source with the rendered Ubuntu Server page. Build or preview the documentation using the repository’s documented workflow, then verify the multiline echo example renders without inserted > characters and still produces valid commands.
