Add accessibility metadata to the test books

[GeorgeKerscher]

We now expect accessibility metadata to be available in EPUB publications. Our test titles should meet this requirement.

[GeorgeKerscher]

Below is the metadata I think that can be cut and pasted into most test books. Some may need to be modified. If there are no page list, for example, the values should be removed.

  <dc:publisher>  DAISY Consortium </dc:publisher>

property="dcterms:conformsTo" id="conf"> EPUB Accessibility 1.1 - WCAG 2.2 Level AA

<meta> id="certifier"> property="a11y:certifiedBy" refines="#conf"> epubtest working group </meta>

Members of the Working Group that wrote the specifications.

I asked Matt to review the metadata section. What is below has Matt's blessing.

<metadata>

Looks great George, I made a tiny edit for formatting (markup has to go in code blocks in these forms, otherwise it appears as rendered HTML with just words and no tags)

[GeorgeKerscher]

I found in the OPF a Schema version number. At first I thought it was to the version of Schema being used. I discovered in the readme file that this is how the version number of the test book is identified.

I will change this to 2.0.0
