Deprecated openssl command option in documentation

Description:

Hi
In the documentation at https://www.postgresql.org/docs/17/ssl-tcp.html, it
says, in 18.9.5. Creating Certificates:
```
To create a simple self-signed certificate for the server, valid for 365
days, use the following OpenSSL command, replacing dbhost.yourdomain.com
with the server's host name:
openssl req -new -x509 -days 365 -nodes -text -out server.crt \
-keyout server.key -subj "/CN=dbhost.yourdomain.com"
```
However, on Ubuntu, running "openssl req --help" shows the following:
```
Output options:
...
-noenc Don't encrypt private keys
-nodes Don't encrypt private keys; deprecated
```
Therefore, I suggest you replace the "-nodes" switch in the command example
to "-noenc".
