### Motivation

While this isn't technically necessary, as all versions of a platform
not explicitly mentioned are assumed to be supported, it's better to be
explicit here.

### Modifications

Add `visionOS(.v1)` to the list of supported platforms.

### Result

Clearer support matrix.

### Test Plan

N/A, this is basically just a documentation change.

Default the configuration parameter

### Motivation

The AsyncHTTPClient transport API has undergone changes in recent months and we didn't bring back the default initializer after we adopted the shared EventLoopGroup, allowing you to create a transport with just `let transport = AsyncHTTPClientTransport()`.

### Modifications

Default the configuration parameter in the initializer to be able to do that. It's already documented to work, but it doesn't.

### Result

Match the documented behavior of being able to use `let transport = AsyncHTTPClientTransport()`.

### Test Plan

Tests still pass.

#32

### Motivation

Recent SwiftPM versions seem to be a bit stricter about using (i.e.,
`import ...`) transitive dependencies without explicitly declaring them
as direct dependencies.

### Modifications

Explicitly depend on the HTTPTypes module from swift-http-types.

### Result

More explicitly declare the dependency graph.

### Test Plan

All tests pass.

### Motivation

We centralize the issues for all the repos in the Swift OpenAPI
Generator project in the generator repo. Using an issue template will
make this even clearer, because it will allow people to use the normal
 workflow to discover the process and provide a link to where to
file their issue.

### Modifications

Add issue template, redirecting to swift-openapi-generator issues.

### Result

When people try and file an issue, they'll be presented with a button
that takes them to the generator repo issues page.

### Test Plan

Manual.

### Motivation

Prep 1.0 - docs.

### Modifications

See above.

### Result

Updated for 1.0.

### Test Plan

Previewed locally.
