Test on Python 3.14 (#90)

* Ignore stubtest warnings about missing `__conditional_annotations__`

I haven't been able to find a lot of information on this attribute. But
it seems like something that should not be included in stub files.

* Ignore unused __conditional_annotations__ rule pre Python 3.14

Pre 3.14 this rule will never match which causes stubtest to complain.
From the stubtest docs [1]:

> Note if an allowlist entry is a regex that matches the empty string,
> stubtest will never consider it unused. For example, to get
> –ignore-unused-allowlist behaviour for a single allowlist entry like
> foo.bar you could add an allowlist entry (foo\.bar)?. This can be
> useful when an error only occurs on a specific platform.

* Only check Python 3.13 on Linux
