Fix autocheck usage in Examples.pod to prevent premature death

[Copilot]

Fixes rt.cpan.org #76714

Problem

Two examples in WWW::Mechanize::Examples.pod were creating WWW::Mechanize objects without explicitly setting autocheck => 0, then attempting to check $mech->success for success/failure. Since autocheck is enabled by default in standalone WWW::Mechanize instances, these examples would die immediately on failed requests and never reach the success check, making the manual check pointless.

Changes

Fixed two examples that had this issue:

1. pb-upload example

# Before
my $mech = WWW::Mechanize->new();
$mech->get($url);
$mech->submit_form(...);
die unless ($mech->success);  # Never reached on failure due to autocheck

# After
my $mech = WWW::Mechanize->new( autocheck => 0 );
$mech->get($url);
$mech->submit_form(...);
die unless ($mech->success);  # Now properly checked

2. quotes.pl example

# Before
my $mech = WWW::Mechanize->new;
$mech->get( "http://www.imdb.com/search" );
$mech->success or die "Can't get the search page";  # Never reached on failure

# After
my $mech = WWW::Mechanize->new( autocheck => 0 );
$mech->get( "http://www.imdb.com/search" );
$mech->success or die "Can't get the search page";  # Now properly checked

Verification

All other examples in the file were reviewed and found to be correctly written:

• Examples without success checks properly rely on autocheck to die on errors (correct behavior)
• Examples that explicitly set autocheck => 1 are already correct
• Examples that check $response->is_success on HTTP::Response objects (not Mechanize objects) are correct

POD syntax validated with Pod::Simple::Checker.

The examples still use new() without autocheck=>0, and then check $mech->success for 
success/failure. Without autocheck=>0, these examples will simply die and never get to the 
test.

@oalders This seems to refer to `Examples.pod`, which probably could use a thorough audit.

Fixes #83

Seems like it would be better to just remove the ->success check.
