Weasyprint forms #3077 (#3084)

This pull request introduces a small but important change to the PDF
conversion functionality. The change ensures that PDF forms are
supported by adding the `--pdf-forms` option to the command lists in two
methods.

*
[`src/main/java/stirling/software/SPDF/controller/api/converters/ConvertWebsiteToPDF.java`](diffhunk://#diff-0e78e0f49bdd0d38127cd04656de55c2eca0b56197e098c6bfceb65e8cc3cff5R75):
Added the `--pdf-forms` option to the command list in the `urlToPdf`
method.
*
[`src/main/java/stirling/software/SPDF/utils/FileToPdf.java`](diffhunk://#diff-337516e2839031154412aa3e7c9a73402f3a630813a1946eae78f8a84e9bbe7fR56):

`convertHtmlToPdf` method.

Closes #3077
