pdfpc: disable REST server
https://github.com/void-linux/void-packages/pull/48959

<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **briefly**

Build with webkit2gtk-4.1, which provides an identical api to webkit2gtk-4.0 except it uses libsoup3.
The REST server functionality requires libsoup2. libsoup2 and libsoup3 cannot be loaded in the same process at the same time.

One of the maintainers recommended just disabling the rest server and building the markdown presentation notes viewer with webkit2gtk-4.1 stating that as far as he knows, he is the only one that actually uses the rest server function. https://github.com/pdfpc/pdfpc/issues/671#issuecomment-1552713117

I was wondering if anyone here that uses pdfpc uses the rest server function?
