[Bug] trailing slashes not preserved in OpenAPI Parser

[franklinharvey]

Describe the bug

Endpoints like api/ or even / are written to IR (and Fern definitions) without trailing slashes

To reproduce

Steps to reproduce the behavior:

1. Have an OpenAPI spec with at least 1 endpoint with a trailing slash
2. Run the command fern generate --docs (or any fern generate command that relies on an OpenAPI spec)
3. Inspect output (in my case resulting docs site)

Example OpenAPI Spec

openapi: 3.0.0
info:
  title: Sample Path Parsing API
  version: 1.0.0
paths:
  /example-without-trailing-slash:
    get:
      summary: Get Example
  /example-with-trailing-slash/:
    get:
      summary: Get Example with trailing

In this example both IR and the Fern def, and therefore client SDKs and docs will have /example-without-trailing-slash and /example-with-trailing-slash

Expected behavior

Trailing slashes should be preserved if they are in the OpenAPI spec
