ADDED: meta_predicate/1 declarations for (',')//2 and (;)//2

This addresses #2366.

Looks good! Oddly the style check is failing now.

I also do not know why the style checks are failing! @gruhn, could you please help with this issue if possible? Thank you a lot!

But it is 'handled', it's passed to a function and then returned. Very curious.

[gruhn]

Hmm, I didn't set up this GitHub action. No idea what these Rust errors mean. I could look into it but your guess is as good as mine :thinking:

The current HEAD commit (40fc4f939261a4dbdc73ef69991fc5d2a4d2bb4e) yields the same problem, so at least this PR would not be a regression.
