Invalid markup in Aldine

[SteelWagstaff]

1. The contact form on the Aldine home page produces HTML validation errors because of how it handles the value property on the input fields.

See https://github.com/pressbooks/pressbooks-aldine/blob/3667d97687de9bbefe8a798ef702f5838a67eb44/partials/contact-form.php#L37-L90

2. Aldine Page Sections produce invalid markup, with some <p> elements opening and closing in unexpected places. This may be a WordPress autop problem? For example, the following input in the page editor:

[aldine_page_section title="Get Started" variant="bordered"]

First issue might be simple fix. Try putting PHP on single line to see if it removes the line breaks in output.
