Fixed code in the POD being displayed improperly

This fixes the issues of the code example being displayed ineligibly (see screenshot below).

In POD, you need to indent all your code samples for them to be rendered as such.

You can install the `Pod::ProjectDocs` (https://metacpan.org/pod/Pod::ProjectDocs) module locally and create a short script that will generate the HTML code that will show how your module's docs will be displayed on search.cpan.org. Or alternatively, you can simply use `perldoc` command to view the POD in the shell.

Here's a short script I often use. Just run it in module's main directory and it generates the HTML I can view.

```perl
#!/usr/bin/env perl

use strict;
use warnings;
use Pod::ProjectDocs;
    
my $lib = 'lib';
Pod::ProjectDocs->new(
    outroot => "/var/www/CPAN/",
    libroot => $lib,
    forcegen => 1,
)->gen;
```
