v3.12.0 (#4282)

* Use `parameterWithMeta` to get parameter data in <ParameterRow>

* Prefer specPath when fetching resolved subtrees in OperationContainer

* Add test for OAS3 callback rendering

* Remove debugger statement

* Pass base resolution URL directly to Swagger-Client subtree resolver

* Remove accidental comment

* Migrate additional options

* Don't default to empty Map when getting subtree

* fix(validateParam): check for ImList type before using count method

* Use `replaceState` to update `urls.primaryName`

This gives us the stateful URL we want, without:
(a) refreshing the page on update
(b) creating a long, useless history for the user
(c) implying that browser history is two-way bound
    to Swagger-UI (it isn't, we don't have a router)

* Add `fn.opsFilter` docs and internal API versioning note

* restrict `x-example` functionality to Swagger 2.0

* polish Authorize + Close buttons

* add tachyons; use it for padding the new Reset button

* v3.12.0

* rebuild dist
