Bumps OpenAPIKit to version 3.0.0-alpha.7 fixing an issue with trailing slashes. (#69)

### Motivation
As discussed in #51, there was an issue with paths containing trailing
slashes. The problem was identified in the
[OpenAPIKit](https://github.com/mattpolzin/OpenAPIKit) dependency. It
was fixed in the PR mattpolzin/OpenAPIKit#274.

### Modifications
This PR updates the OpenAPIKit dependency version from `3.0.0-alpha.6`
to `3.0.0-alpha.7` ([available
here](https://github.com/mattpolzin/OpenAPIKit/releases/tag/3.0.0-alpha.7)),
which includes the mentioned PR.

### Result
If a path ends with a trailing slash, such as `foo/bar/`, the generated
functions will now correctly call the path `foo/bar/` instead of (as
previously) `foo/bar`.

### Test Plan
Replaced an endpoint in the reference test to use a path with a trailing
slash.

### Resolves
- Resolves #51
