Issue description

After upgrading to 2.7.0 version, the pdf generation fails on non-dev/test environment with the following error:

No such file or directory @ apply2files - /tmp/wicked_header_pdf20230905-21-mm5ta8.html

backtrace:

vendor/bundle/ruby/2.7.0/gems/wicked_pdf-2.7.0/lib/wicked_pdf.rb:112 delete

vendor/bundle/ruby/2.7.0/gems/wicked_pdf-2.7.0/lib/wicked_pdf.rb:44 pdf_from_string

The issue seems to be related with the #clean_temp_files method.

Expected or desired behavior

• pdf generation succeeds
• #clean_temp_files checks if file exists before trying to delete
